Tube Fitting Sleeve and Nut Kits

Tube Fitting Sleeve and Nut Kits

Everything you need to create a tight seal between a metal tube and a Yor-Lok fitting

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

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

On-Off Valves

Start and stop flow through a line

Pressure-Relief Valves

Pressure-Relief Valves

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

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
