Gradually open and close to control the volume of air and liquids though a line

Air Valves

Fill tanks, tires, and other pressurized equipment

Diverting Valves

Diverting Valves

Redirect flow between ports

Check Valves

Permit flow in only one direction by closing when flow stops or reverses

Valve Repair Kits

Valve Repair Kits

Maintain valves with replacement parts such as seals, plungers, and springs

Flow-Regulating Valves

Flow-Regulating Valves

Maintain the set flow rate of fluid through your system

Orifice Valves

Restrict the flow of liquids and gases to precisely control rate and pressure

Sampling Valves

Sampling Valves

Drain a small amount of fluid for inspection without disrupting flow

Valve Mounts

Match standard NFPA mounting patterns to connect valves with multiple ports

Directional Control Valves

Directional Control Valves

Manage the flow of fluids to move equipment in air- and hydraulic-powered systems

Vacuum Breakers

Vacuum Breakers

When pressure drops, vents open to prevent suction from drawing liquid back upstream

Air Chucks

Connect air hose to Schrader valves, which are common on tires and hydraulic systems

Manifolds

Distribute air or fluid to multiple places from a single source; also called headers

Tube and Tube Fittings

Tube and Tube Fittings

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment

Hose and Hose Fittings

Hose and Hose Fittings

Flexible and stronger than tubing; often used to convey liquids and gases under pressure

Flame Arresters

Flame Arresters

Absorb heat from a fire in your gas pipeline to stop it from traveling back to the gas source

Junction Blocks

Junction Blocks

Organize and separate multiple lines in a pipe system; air and fluid flow through the threaded holes

Pressure-Regulating Valves

Pressure-Regulating Valves

Reduce inlet pressure to a lower outlet pressure to protect sensitive equipment

Pressure-Relief Valves

Pressure-Relief Valves

Protect equipment by opening at a set pressure and closing when the pressure drops; for repeated use

Mufflers

Reduce noise and filter exhaust fumes

Steam Traps

Extract condensation from lines without losing any steam

Tank Mixing Nozzles

Tank Mixing Nozzles

Circulate liquid in tanks to keep solids from settling

Lubricating

Coolant Dispenser Hose and Fittings

Coolant Dispenser Hose and Fittings

Snap together and position to deliver coolant, oil, water, or air in any direction

Power Transmission

Hydraulic Check Valves

Hydraulic Check Valves

Open to allow hydraulic fluid flow in one direction and close when flow stops or reverses

Fastening and Joining

Welding Gas Flashback Arresters

Welding Gas Flashback Arresters

Attach to your gas welder to extinguish flames and stop reverse gas flow
