Low-Pressure Stainless Steel Butt-Weld Pipe Fittings

Also known as Schedule 10 fittings, these are thin and lightweight. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow.

Short 90° Elbow Connectors

Butt Weld

304/304L Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

316/316L Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

Stub-End Straight Adapters

Straight Adapter

Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

Low-Pressure Aluminum Socket-Connect Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings are aluminum, which is lightweight with good corrosion resistance.

Low-Pressure Stainless Steel Press-Socket Pipe Fittings

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat. Fittings have an internal stainless steel gripping ring and rubber O-ring that create a seal when crimped. They are designed to leak if fittings have not been crimped; a colored dot marks the leak path so it's easy to spot unsealed connections. All of these fittings are made of 304 stainless steel to resist corrosion from frequent exposure to water and fuels. They’re often used for water processing lines, heating and cooling systems, and fuel lines. They are comparable to Viega MegaPress fittings. Fittings meet ANSI/ASME B31 code requirements for use in pressure piping systems.

Crimping Tools

Image of Product. Front orientation. Tube Crimpers.

Crimping tools seal fittings in less than five seconds. These tools are cordless, so you can take them to any job. Connect the jaw or ring that matches your pipe size to these tools, then pull the trigger to crimp the fitting. The pivoting head lets you access connections from any angle.

Jaw and ring sets include three jaws, three rings, and one ring actuator jaw. Jaws are for pipe sizes 1/2 to 1; they fit directly into the crimping tool. Rings are for pipe sizes 1 1/4 to 2; clip the ring around the fitting and use the ring actuator jaw and crimping tool to press the open ends together.
