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

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

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

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.

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.

Mount these manifolds on the end of a hose line to distribute air, water, or hydraulic fluid to three locations from a single supply source.

When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air or fluid to five locations from a single supply source.

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

Use these CGA fittings to connect welding hose to pressure regulators and torches.

Tighten these threaded fittings with your hands for a secure connection in testing, flushing, venting, and plugging applications—no tools, tape, or sealant required.

Connect these orifices to threaded pipe, or insert them into threaded holes.

Also known as orifice plates, these mount between orifice flange unions.

For installation through thick insulation, these valves have an extra-long stem.

For chemical-processing applications in confined areas, these valves have a low-profile handle to fit in tight spots. A rubber seal and a plastic body stand up to aggressive, corrosive solutions.

The most chemical-resistant threaded valves we offer, these have a PTFE seal and an alloy body that can withstand extremely aggressive and corrosive chemicals, such as methyl ethyl ketone and toluene.

Insert tubing into the fittings on these valves—no heat, solder, or flux required. To withstand aggressive and corrosive solutions, they have a chemical-resistant fluoroelastomer seal and a plastic body.

Also known as gate valves, these valves gradually open and close to prevent system damage from suddenly starting and stopping flow.

Built to withstand the extreme cold of liquid nitrogen and liquid oxygen, these valves are cleaned and bagged for high-purity applications.

For three times the flow of butterfly valves, these have a ball valve design.

Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage.
