This Swagelok® male pipe weld fitting has a 1" standard Swagelok compression fitting on one side (nut and ferrule set included), and a 1" (schedule 80) pipe on the other end. The pipe end has a 37.5° chamfer for ease of welding.

See the second image for dimensions.

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.
