Smooth-Bore Seamless Stainless Steel Tubing

Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.
304 stainless steel has very good corrosion resistance.
316 stainless steel offers excellent corrosion resistance.
Tubing that meets ASTM specifications adheres to international standards for dimensions and materials.

Thick-Wall (Rigid) Steel Conduit
For technical drawings and 3-D models, click on a part number.

This impact- and crush-resistant conduit is also known as galvanized rigid conduit (GRC). It has one threaded male end; the other end has a threaded female connector.
5-ft. lengths can be shipped via small-parcel carrier.

Attach medium-wall (IMC) and thick-wall (rigid) steel conduit to a knockout in an outlet box or enclosure.
NPT female × NPSM male straight adapters are also known as hubs. They have an insulated throat to protect wire and cable from abrasion when being pulled. Use in wet or dry locations.
