Fluid Handling

On-Off Valves

Start and stop flow through a line

Air Valves

Fill tanks, tires, and other pressurized equipment

Flow-Regulating Valves

Flow-Regulating Valves

Maintain the set flow rate of fluid through your system

Directional Control Valves

Directional Control Valves

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

Float Valves

Open or close a pipe connection when liquids in a container reach a set level; also known as ballcocks

Valve Mounts

Match standard NFPA mounting patterns to connect valves with multiple ports

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

Hose Fittings

Create threaded, barbed, quick-disconnect, and other types of connections between lengths of hose

Hose Nozzles

Control flow while dispensing water, fuel, hydraulic fluid, coolant, and chemicals

Tube and Tube Fittings

Tube and Tube Fittings

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

Junction Blocks

Junction Blocks

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

Pressure-Relief Valves

Pressure-Relief Valves

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

Pressure-Regulating Valves

Pressure-Regulating Valves

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

Power Transmission

Hydraulic Check Valves

Hydraulic Check Valves

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

Hydraulic Flow-Adjustment Valves

Hydraulic Flow-Adjustment Valves

Turn the knob to gradually adjust the flow of hydraulic fluid

Building and Machinery Hardware

T-Slotted Framing and Fittings

T-Slotted Framing and Fittings

The most versatile system, attach fittings along the continuous slots to build virtually anything
