About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Standard-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 40 plastic pipe–they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

Fittings for drinking water meet NSF/ANSI Standard 61.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).

To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. Fittings that meet ASTM D1784, ASTM D1785, and ASTM D4066 adhere to specifications and testing requirements for material quality.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Union Straight Connectors, Female Threaded Pipe

For Use With: Drinking Water, Water
Maximum Temperature: 140° F
Specifications Met: See table
Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic
Flanges: Use Class 150 PVC Plastic

Unions separate into three pieces so you can access your line without unthreading pipe connections.

Press-Connect Fittings for Copper Tubing

For Use With: Drinking Water
Maximum Pressure: Fittings compatible with Viega ProPress or Viega ProPress XL-C: 200 psi @ 72° F
Fittings compatible with Viega Pex or Viega PureFlow Press: 100 psi @ 72° F
Temperature Range: 0° to 250° F
Tubing: Fittings compatible with Viega ProPress or Viega ProPress XL-C: Use with K, M, L copper
Fittings compatible with Viega Pex or Viega PureFlow Press: Use with hard polyethylene plastic
Specifications Met: See table

Crimp these fittings to copper tubing with a crimping tool (sold separately). An O-ring on the inside of the fitting creates a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings. Fittings have good corrosion resistance. They meet NSF/ANSI safety standards for use with drinking water systems.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
