Vibration-Resistant Compression
Fittings for Stainless Steel Tubing
- For Use With: Acetylene, Air, Butane, Compressed Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Helium, Hydraulic Fluid (Petroleum Base), Kerosene, Mineral Oil, Natural Gas, Nitrogen, Propane, Soap Solutions
- Temperature Range: -10° to 400° F
- Tubing: Use with seamless 316Ti or 321 stainless steel
- Specifications Met: DIN 3861
Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps. However, rubber sleeves can’t withstand temperatures as high as metal ones. To create the strong seal, tighten the included nut. These fittings are made of 316 stainless steel, so they have excellent corrosion resistance. They’re also known as flareless fittings. All meet DIN 3861, which is an international standard for compression tube fitting specifications.
BSPP and metric male threads have a gasket to prevent leaks.
