Tube Fitting Clamps

Tube Fitting Clamps

Quickly secure connections between tube fittings, including sanitary and high-vacuum fittings

Tube Sampling Ports

Tube Sampling Ports

Take samples from sanitary tubing without pausing or contaminating your line

Hose Fittings

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

Hose

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

Manifolds

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

Pipe and Pipe Fittings

Pipe and Pipe Fittings

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

Junction Blocks

Junction Blocks

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

Tube Repair Clamps

Tube Repair Clamps

Mend small holes, cracks, and full-circle breaks in tubing without dismantling your system

On-Off Valves

Start and stop flow through a line

Check Valves

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

Orifice Valves

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

Flow-Adjustment Valves

Flow-Adjustment Valves

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

Diverting Valves

Diverting Valves

Redirect flow between ports

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

Lubricating

Grease Fitting Adapters

Grease Fitting Adapters

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

Fastening and Joining

Brazing Rings

Snap into metal pipe and tubing to form leak-resistant joints more quickly than with hand-fed alloys

Facility and Grounds Maintenance

Air Admittance Valves

Air Admittance Valves

Allow air into drain, waste, and vent systems so you don't have to vent plumbing to the outdoors
