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.

Caps for tubing have a nut and a sleeve so you can close off the end of your tubing in place of a fitting. Caps for fittings replace the nut and sleeve of an existing fitting.
