Brass Push-to-Connect Fittings for Copper Tubing

- Tubing: Use with K, M, L copper, polyethylene plastic, CPVC
Connect these fittings to copper tubing with a push—no heat, solder, or flux required. They have an internal gripping ring and O-ring that hold the fitting secure. They also come with a tube support or retainer if you want to use them with polyethylene plastic (PEX) tubing. They are also known as instant fittings. Fittings are brass for good corrosion resistance. They are compatible with SharkBite® fittings. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61.

A release clip is required to disconnect the fitting from the tubing.
Use release clips with a depth gauge to mark how far you need to insert your PVC pipe into its fitting to ensure a watertight connection.

Plastic Push-to-Connect Fittings for Copper Tubing

- For Use With: Drinking Water
- Temperature Range: 35° to 180° F
- Tubing: Use with K, M, L copper, polyethylene plastic
- Specifications Met: NSF/ANSI 61
Made of plastic, these fittings are lighter than our brass push-to-connect fittings. They connect to copper tubing with a push—no heat, solder, or flux required. They have an internal gripping ring and O-ring that hold the fitting secure. To disconnect, push on the release ring and pull the tubing out of the fitting. They are also known as instant fittings. Fittings come with a tube support if you want to use them with polyethylene plastic (PEX) tubing. They meet NSF/ANSI 61 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.
