How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Low-Pressure Steel Unthreaded Pipe Flanges
Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (sold separately) to create an access point in a pipe line. Flanges are for use with low-pressure applications in noncorrosive environments.
Butt-weld flanges are also known as weld-neck flanges. The flange neck has a beveled end that, when flush to pipe, creates a trough for a strong weld.
Slip-on weld flanges have no internal stop. Slide a pipe through the flange and weld on both sides.
Cap flanges are also known as blind flanges.

Press-Connect Fittings for Copper Tubing
- For Use With: Drinking Water
- Maximum Pressure: 200psi @ 72° F
- Temperature Range: 0° to 250° F
- Tubing: Use with K, M, L copper
- 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.
Straight adapters with flanged end bolt to equipment or other flanged connections found on pumps and valves to create a convenient access point.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
