Designed for high-purity processes, this tubing is made without plasticizers like DEHP that can contaminate the fluid passing through it. It meets USP Class VI specifications for material testing; it is not for use in medical applications. Tubing is clear, so you can monitor flow. It’s also flexible and easily bends around objects.
Tubing with braid reinforcement has extra strength to handle higher pressures than nonreinforced tubing.

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.
