These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Use these tube-end weld nuts with left-hand threaded fasteners.

A smooth base on these metric nuts provides more contact with the mating surface than weld nuts with projections

These steel nuts have a short collar to fit in low-clearance areas.

Projections on the base concentrate the weld and provide room for heat to dissipate.

The three weld points on these metric hex nuts create a secure hold on a steel surface.

You can weld these metric nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold.

Irregularly shaped threads in these nuts form a tight grip, preventing screws from backing out in vibration-heavy environments.

Weld these nuts to stainless steel surfaces.

To protect their threads from deforming, these steel nuts have a projection that concentrates your weld and creates room for heat to dissipate. An offset barrel lets you position threads near the edges and corners of uncoated steel sheets.

Install metric threads in channels and other tight spaces where round-base weld nuts won’t fit.

Projections on the base of these nuts concentrate your weld and create room for heat to dissipate, protecting threads from deformation. Made of 18-8 stainless steel, these nuts withstand mild chemicals and can be used in wet and outdoor environments.

Threads float inside the retainer of these metric nuts so you can install a bolt at a slight angle to align with off-center parts.
