Use these O-rings with brass compression tube fittings that have BSPP male threads. They create a seal on the BSPP male threads to guard against leaks.

Create airtight seals in high-vacuum systems by placing these rings between two claw-clamp (ISO-K) or bolt-together (ISO-F) fittings.

Also known as no-hub couplings, these have a one-piece sleeve with a stop in the center, so you know your pipe is always aligned correctly.

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Also known as Code 61 SAE hydraulic flanges.

The grooved ends on these iron fittings connect to pipe with a clamp to easily install piping systems.

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT).

Extreme pressures are no problem for these heavy-duty brass fittings.

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system.

When space is at a premium choose these compact fittings.

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

Use these fittings in extreme-pressure conditions up to 15,000 psi.

Also known as Code 61 SAE hydraulic flanges, these let you create an access point in a high-pressure hydraulic line.
