Push in fittting

Types of push fit fittings

Generally, the push fit fitting provides two functions: connecting two pipes together and connecting a pipe to another type of plumbing component, such as a valve or faucet.

• Equal coupling

  An equal coupling is a push-fit fitting that connects two pipes of the same diameter. This fitting is typically used when a single run of pipe needs to be extended.

• Reducer

  A reducer push-fit coupling connects pipes of different diameters. It changes the pipeline system from a larger to a smaller bore or vice versa. This fitting can be used to connect a new appliance to existing piping or to allow for future expansion of the piping system.

• Branch tee

  A branch tee push fit fitting is used to connect a service line to a main line. It is usually outfitted with a cap or plug on the side to allow for future service. This fitting can also be used to change the direction of a pipeline.

• Saddle

  A saddle push-fit coupling is typically used to connect a service line to a main line without cutting the main line. This fitting 'straddles' the other pipe and is usually clamped in place. Adding a service line for a new irrigation system or underground water source is common.

• Elbow

  An elbow push fit fitting is used to change the direction of a pipeline, typically by 90 or 45 degrees. Elbows can be used to route piping around obstacles or to change the alignment of a drop or horizontal run. In addition, the push-fit method allows for quicker and easier connections than traditional soldered or welded joints.

• Swivel

  A swivel push-fit coupling allows for rotation of the connected pipes. It is commonly used where termination is required, or a joint must accommodate relative motion. A push-fit swivel is similar to an elbow but allows for the connection of two pipes that can rotate relative to one another.

• Cap

  A cap push-fit fitting is used to close or cap off a section of pipe. It is often used to create a future access point or to close off a branch line from a main header.

Specification and maintenance of push fit

• Temperature: The temperature range of push-fit fittings varies depending on the material. For CPVC, it can be up to 200 °C. PEX can handle temperatures up to 100 °C, and Polypropylene can work between 0 and 95 °C. In terms of the working environment, push-fit plumbing fittings can be used in a wide range of temperatures.
• Pressure: Pressure push-fit plumbing works very well under pressure. For CPVC, it can withstand up to 2000 pounds. PEX push-fit plumbing can handle pressures up to 80 PSI. The pressure tolerance of push-fit plumbing is different according to the material.
• Flow: When it comes to the flow, push-fit plumbing fittings can deal with high flow. For CPVC, the internal diameter is 0.5/0.75/1. The flow rate is 629/785/929. For PEX, the internal diameter is 3/8, 1/2, 3/4, and the flow rate is 556, 783, and 1026. Generally speaking, the bigger the internal diameter is, the more it can support the passage of water.

Maintenance method

• Regular inspection: Check regularly to ensure that there are no joints loosening, leaks, etc. In case of any problems, they should be addressed in time.
• Clean: Clean the surface of push-fit plumbing fittings to keep them hygienic. Avoid using corrosive cleaners or abrasive articles that could damage their surfaces.
• Lubricate: Regularly lubricate the sealing rings and other components of push-fit plumbing with appropriate lubricants to keep them flexible and seal well.
• Avoid overstress: When installing and using, avoid overstressing the push-fit fittings to prevent deformation, breakage, etc.
• Temperature and pressure: Pay attention to the temperature and pressure used; avoid using them under high temperature and pressure to prevent them from aging and damage.

Scenarios of push-in fitings

Despite being commonly used in the plumbing industry, push fit connectors have found excellent applications in other fields.

• Hydroponics and Agriculture

  Push-fit connectors provide a low-maintenance and reliable solution for connecting pipes in hydroponic systems. They enable precise control of nutrient delivery, water flow, and system scalability, ensuring efficient plant growth and minimizing disruptions in hydroponic farming.

• Drinking Water Distribution

  Push-fit connectors ensure a reliable and leak-free water distribution system in drinking water supply systems. Quick installation, adaptability to changing demands, and robust connections contribute to the efficiency and integrity of the plumbing infrastructure, supporting safe and accessible drinking water delivery.

• Compressed Air Systems

  Pneumatic Systems: Push-fit connectors offer secure and efficient pipe connections in compressed air systems and pneumatic networks. They enable smooth air flow, minimizing pressure loss, and facilitating the operation of tools and equipment, thereby enhancing productivity in industrial applications that rely on compressed air and pneumatic systems.

• Automotive Industry

  In automotive applications, push-fit connectors play a crucial role in ensuring efficient fluid transfer. They provide reliable connections for systems like fuel lines, cooling systems, and air intake, contributing to optimal vehicle performance and smooth operation.

How to choose push in fittings

• Application requirements:

  Before sourcing push fit plumbing fittings for retail, it is essential to get an in-depth understanding of the application requirements. Consider the operating pressure and temperature of the application. If the fittings are to be used in high-pressure or high-temperature applications, the store buyer will need to get fittings that are designed for those conditions. Also, consider the type of fluid the fittings will handle. Store buyers will need to source fittings that are compatible with the specific fluid to avoid leaks or degradation.

• Quality and certification:

  When choosing push fit plumbing fittings for retail, store buyers should look for high-quality fittings that meet relevant standards and certifications. Fittings that have been tested and certified to meet industry standards are likely to perform better and last longer. Quality push fit plumbing fittings also ensure the health and safety of end users. Store buyers should look for fittings with reliable locking mechanisms. A reliable locking mechanism reduces the risk of accidental disassembly and ensures a secure connection throughout the product’s lifetime.

• Sizes and compatibility:

  When sourcing push fit plumbing fittings for retail, store buyers should offer a range of sizes to accommodate different customer needs. Also, they should choose fittings that are compatible with commonly used pipes in the target market. This helps avoid customer complaints and return rates. Additionally, when shopping for store inventory, retail buyers should opt for fittings that are easy to install. They should have clear instructions and be compatible with commonly used tools. This will appeal to customers looking for straightforward DIY solutions.

• Price and warranty:

  Consider the price and warranty of the fittings when shopping for retail inventory. Store buyers should get fittings that offer good value for money without compromising quality. Conduct a market comparison to get a competitive price that appeals to target customers. Additionally, buyers should choose fittings with a reasonable warranty period. It shows the manufacturer's confidence in the product and provides customers with added protection.

Push in fitting Q & A

Q1: Are push fittings better than compression?

A1: Compression fittings are traditional plumbing fittings that are still widely used today. While compression fittings create strong seals, they are not as strong as push-fit fittings. Therefore, push-fit fittings are better than compression in this context.

Q2: Are push-fit connectors reliable?

A2: Push-fit connectors are reliable. When properly installed, they can last for decades without needing to replace or maintain them.

Q3: Can you use oil push fittings?

A3: Generally, use oil push-fit fittings constructed from materials compatible with the specific oil used. For example, some oils may be chemically aggressive and require push-fit fittings that resist such aggression. Additionally, ensure that the push-fit fittings are suitable for the temperature and pressure conditions of the oil application.

Q4: Do push-fit fittings need to be glued?

A4: In most cases, push-fit PVC fittings are used with unground pipe.

Q5: How do push-fit fittings work?

A5: Push-fit plumbing fittings go through three stages. The first stage is to insert the pipe into the fitting. The second stage is to grasp the pipe in the fitting with a collet. The third stage is to create a seal with an O-ring.
