This Swagelok® reducing tubing adapter fitting has a 1/8" standard Swagelok compression fitting on one side, and a 3/8" tubing adapter on the other. The fitting is made of 316 stainless steel. The Swagelok side of this adapter receives a 1/8" OD tube. The 3/8" tubing end uses an outward facing nut and ferrule set which then connects to a threaded male swagelok fitting. A 3/8" nut and ferrule set is required and must be purchased separately.

These industry standard Swagelok compression-type fittings and components are precision manufactured and offer a gas-tight, metal-on-metal seal. They are available in standard fractional tubing sizes for making up stainless steel tubing. Polished surface finishes and high purity materials virtually eliminate these fittings as a source of system contamination.
