Strainers catch debris in your pipeline, preventing damage to valves, pumps, nozzles, and other sensitive equipment. They are designed for medium-pressure applications. Strainers have a threaded drain with a plug that provides access to the screen without disconnecting your line. They have good corrosion resistance.
Strainers with socket-connect tube connections are for use with copper tubing; to connect, insert tubing into the socket and weld to create a permanent, leak-tight connection. Copper tube size is the accepted designation of the copper tubing industry, not the actual OD.

Check Valves with Solder-Connect Fittings
- For Use With: Steam, Water
- Disc Material: Bronze
- Seal Material: Bronze
Solder these valves to copper tubing for a permanent, leak-tight connection. They open to allow flow in one direction and close when flow stops or reverses. All have a removable cap that provides easy access to internal components for maintenance.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
