Fluid Handling

Pipe and Pipe Fittings

Pipe and Pipe Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases through your facility

Tube Fittings

Make threaded, push to connect, barbed, and other types of connections between lengths of tube

Hose Fittings

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

Hose Nozzle Swivels

Hose Nozzle Swivels

Rotate to prevent hose from kinking, twisting, and wearing

Manifolds

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

Junction Blocks

Junction Blocks

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

Air Chucks

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

Orifice Valves

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

On-Off Valves

Start and stop flow through a line

Drain Valves

Vent air or discharge liquids to remove excess fluid from your system

Air Valves

Fill tanks, tires, and other pressurized equipment

Expansion Plugs

Expansion Plugs

Seal pipe and tubing lines when checking for leaks

Pressure Test Fittings

Pressure Test Fittings

Create a temporary connection point for gauges and other testing equipment

Breather Vents

Maintain even pressure and vacuum as temperatures change by allowing airflow in tanks and enclosures

Fastening and Joining

Thread Adapters

Thread Adapters

Join threads of a different type, size, and gender

Lubricating

Grease Fitting Adapters

Grease Fitting Adapters

Mate grease fittings when the sizes and thread types don't match

Grease Fitting Manifolds

Grease Fitting Manifolds

Lubricate multiple points with the same amount and type of grease using one grease fitting

Oil Fittings

Install in engine blocks and other machinery to pour in oil while keeping dust out

Building and Machinery Hardware

Protective Caps

Protective Caps

Protect just about anything, including pipe, flanges, screws, and posts

Protective Plugs

Protective Plugs

Insert into holes in pipe, containers, panels, and parts to keep out debris

Electrical
