Pipe Fittings for Carbon Dioxide

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.

High-Pressure Nipples for Compressed Gas

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut to make a threaded connection.

Flow-Control Orifices

Threaded Flow Control Orifices

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

Compression Flow-Control Orifices

Compression fittings bite down on the outside of hard metal tubing for a secure connection.

Flange-Mount Flow-Control Orifices

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

Press-In Flow-Control Orifices

Press these orifices into machined holes in connectors, manifolds, and other custom parts.

Flow-Control Orifices for Chemicals

Made of PVC, these orifices have excellent resistance to a wide range of corrosive chemicals.

On/Off Valves

Compact Threaded On/Off Valves for Chemicals

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.

Miniature Threaded On/Off Valves for Chemicals

To withstand aggressive and corrosive solutions in miniature chemical-processing pipelines, these tiny valves have a chemical-resistant fluoroelastomer seal and a corrosion-resistant 303 stainless steel body.

Ultra-Chemical-Resistant Threaded On/Off Valves

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.

Threaded Isolation On/Off Valves for Chemicals

Attach gauges or sensors to these valves so you can remove them for maintenance and calibration without depressurizing your line. They are also known as block and bleed valves.

Easy-to-Install Threaded
On/Off Valves for Chemicals

For fast installation and removal from pipelines, these valves have union fittings that disassemble into multiple pieces. All have a fluoroelastomer seal and a plastic body that can stand up to aggressive and corrosive solutions in chemical-processing applications.

Easy-Clean Threaded On/Off Valves for Chemicals

There’s no need to unbolt these valves for cleaning—remove the valve handle and slide the valve apart for inline access to internal components. Also known as elliptical valves, they have a fluoroelastomer seal and a polypropylene body to withstand aggressive and corrosive solutions in chemical-processing applications.

Easy-Maintenance Threaded
On/Off Valves for Chemicals

No need to remove these valves from your line to access their internal components—the three-piece bolted body comes apart. Ideal in chemical-processing applications, the seal and polypropylene body stand up to aggressive and corrosive solutions.

Easy-to-Install Socket-Connect
On/Off Valves for Chemicals

Streamline your installation and removal process. These valves give you the leak-tight permanent connection of a socket connect with the ease of fittings that come apart.

On/Off Valves with Barbed Fittings for Chemicals

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a plastic body and a chemical-resistant seal.

On/Off Valves with Push-to-Connect
Fittings for Chemicals

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.

Threaded Gradual On/Off Valves

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

Socket-Connect Gradual
On/Off Valves for Chemicals

These valves have socket-weld connections for bonding to unthreaded male plastic pipe.

Threaded Gradual On/Off Valves for Chemicals

For use with threaded pipe, these valves have NPT connections.

Flanged Air-Driven On/Off Valves for Chemicals

With a ball-valve design, these valves can handle three times the flow of butterfly valves.

Flanged Motor-Driven On/Off Valves for Chemicals

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

Severe-Duty Air-Driven On/Off Valves for Chemicals

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

Pipeline Fluid Blockers

Also known as pipe blinds, these fluid blockers fit between two flanges to stop flow, so you can work downstream without draining the system.
