High-Pressure
Minimal-Spill Quick-Disconnect
Hose Couplings for Hydraulic Fluid

Use these couplings at pressures up to 10,000 psi. Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close together, reducing fluid loss when connecting and disconnecting the line. They are compatible with High-Pressure Minimal-Spill-shape plugs and sockets.

Quick-Disconnect Hose
Couplings for Coolant

Couplings consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are designed for coolant applications up to 200 psi. Also known as coolant-line mold couplings.

Tube Plugs for Heat Exchangers

Plug leaky internal tubes in heat exchangers with these two-piece ring and pin sets.

Pressure and Vacuum Monitoring and Control

Expansion Plugs for Tubing

These plugs are designed for metal and rigid plastic tubing.

Compact Pressure-Relief
Valves for Air

Less than a quarter of the height of standard pressure-relief valves for air, these are often installed on air tanks in low-clearance areas.

Breather Vents

Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks.

Grease Fittings

Inject lubricant into motors, bearings, engine blocks, and all kinds of machinery.

Grease Fitting Assortments

Assortments contain straight, 45° elbow, and 90° elbow fittings.

Flow-Stop Grease Fittings

Prevent damage to bearing seals caused by over-lubrication—these fittings automatically stop grease flow when pressure is within the shut-off range.

Leakproof Grease Fittings

Keep thin grease from leaking out—the check valve on these fittings has a Buna-N seat that creates a tighter seal than check valves on other grease fittings.

Flush-Style Grease Fittings

Use these fittings in tight spaces where protruding fittings won't work.

Button-Head Grease Fittings

Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won't pop off when adding grease.

Pin-Style Grease Fittings

The pins on these fittings lock with dispensing tips for pin-style fittings to create a tight seal.

Grease Fittings for Unthreaded Holes

Drive these fittings into unthreaded holes. They're also known as hydraulic grease fittings.

Self-Tapping Grease Fittings
for Unthreaded Holes

Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. They're also known as hydraulic grease fittings.

Flush-Style Grease Fittings
for Unthreaded Holes

Use these fittings in tight spaces where protruding fittings won't work. Drive them into unthreaded holes.

Self-Tapping Flush-Style Grease
Fittings for Unthreaded Holes

Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. Use these fittings in tight spaces where protruding fittings won't work.

Grease Fitting Tools
for Unthreaded Holes

Tap these tools once or twice with a hammer to install fittings.

Grease Fitting Dust Caps

Keep standard grease fittings free of dirt and moisture.

Grease Fitting Cleaning Tools

Fill these tools with light oil, then tap with a hammer to open clogged fittings.

Remote-Access Grease Fittings

Access difficult-to-reach lubrication points from up to 10 ft. away.

Grease Fitting Tools
for Threaded Holes

Remove worn fittings and repair threaded holes.

Grease Fitting Manifolds

Lubricate multiple points from a single location.

Grease Fitting Adapters

When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.

Oil Fittings

Oil Fittings for Unthreaded Holes

Drive these fittings into unthreaded holes.

Oil Fittings

Install these fittings into threaded holes.

Grease-Filled Tubing

Don’t wait for grease to travel through a new service line—install this grease-filled tubing between the pump and a lubrication point to begin lubricating immediately.
