Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Also known as Code 61 SAE hydraulic flanges.

Use these corrosion-resistant fittings in a low-pressure pipe line.

Even in temperatures as low as -46°, these A350 LF2 steel flanges won’t become brittle, so they absorb impact better than other low-pressure steel flanges.

Forged for extra strength, these heavy duty unthreaded flanges can withstand high-pressure applications.

With thicker, stronger walls than our standard-wall butt-weld pipe fittings, these fittings stand up to your high strength applications.

Use these fittings for low-pressure applications in noncorrosive environments.

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

The inside of these fittings won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC fittings.

Create a leak-free, durable connection in plastic tanks, walls, or panels without gaskets or sealants.

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets.

For use in high-vacuum systems, these fittings use a metal reinforced O-ring to create an airtight seal. Also known as KF, QF, and NW fittings, they’re used for high-vacuum applications such as vacuum coating and heat treating, leak testing, and analyzing gases.

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

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

Add corrosion-resistant threads to stainless steel sheets, even in spaces with low clearance.

With a slim base and a short barrel, these corrosion-resistant weld nuts fit in tight spaces and in low-clearance areas.

Add a pair of same-size threads to sheet metal while only welding once.

Projections on the base of these steel nuts concentrate your weld and create room for heat to dissipate, protecting threads from deforming. Weld them to uncoated steel channels and other tight spaces where round-base weld nuts won't fit.

Slim at the base, these weld nuts fit in channels and other spaces too tight for round-base weld nuts. Weld them to stainless steel surfaces to add strong, permanent threads that resist corroding from chemicals.

An offset barrel allows you to position threads near edges and corners.

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 corrosion-resistant threads in sheet metal to create a 90° joint.
