About Pipe and Fittings

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

Precision Compression Fittings for Stainless Steel Tubing

For Use With: Air, Cutting Oil, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Mineral Oil, Natural Gas, Steam, Water
Temperature Range: -420° to 1200° F
Tubing: Use with welded or seamless 304 or 316 stainless steel that meets ASTM A213, ASTM A249, or ASTM A269
Compatible With: Parker CPI

Made to tighter tolerances than other compression fittings, these are designed for high-precision applications. Also known as instrumentation fittings and flareless fittings. They come with a nut and a single sleeve (ferrule). The sleeve bites into tubing as you tighten the nut to create a strong seal. Fittings are 316 stainless steel for excellent corrosion resistance. A molybdenum disulfide coating on the nut acts as a lubricant for easy installation.

Straight Adapters, Tube Stem × Male NPT Threaded Pipe

Fittings with tube stem insert into the tube end of another fitting in place of a length of tubing.

Nickel-Plated Brass Compression Fittings for Copper Tubing

For Use With: Air, Cutting Oil, Diesel Fuel, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Lubricants, Mineral Oil, Natural Gas, Steam, Water
Temperature Range: -75° to 550° F, except 90° elbow adapters with BSPP threads are 0° to 170° F
Tubing: Use with copper
Specifications Met: DIN 3861, except nuts meet DIN 3870

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings. They have a single sleeve (ferrule) made of plain brass that gently bites into copper tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. These fittings are also known as flareless fittings. All meet DIN standards for tube fitting dimensions.
