Hose and Hose Fittings

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Chemicals

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Barbed Hose Fittings for Coolant

Designed for coolant applications up to 200 psi, these fittings have a standard barbed end that slides into hose and secures with a clamp.

Beaded Hose Fittings for Coolant

A single rounded bead grips onto hose just like a barb, but has no sharp edges that could cut or damage soft hose. Slide the beaded end into hose and secure with a clamp. Use in coolant applications up to 300 psi.

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.

High-Temperature Coolant Hose

Silicone rubber gives this hose, often called radiator hose, the ability to handle high-heat conditions.

High-Temperature Vacuum-Rated Coolant Hose

Not only can this hose withstand high temperatures, it won't collapse in low-vacuum applications. It's also known as radiator hose.

Coolant Hose

Commonly known as radiator hose, this hose is for low-pressure coolant applications.

High-Pressure Braided Coolant Hose

Instead of a rubber cover, this hose has a stainless steel braid for excellent strength in high-pressure applications.

Flexible Coolant Hose

With a tighter bend radius than other coolant hose, this hose can twist and turn around equipment.

Barbed Swivels for Hose Nozzles

Slide the barbed end of these swivels into your dispensing hose and connect with a clamp. They rotate before and after installation as needed to prevent hose from twisting, kinking, and wearing prematurely.

Threaded Swivels for Hose Nozzles

Connect these swivels to the threaded end of your dispensing hose. They rotate before and after installation as needed to prevent hose from twisting, kinking, and wearing prematurely.

Coolant Hose Nozzles

Dispense and control the flow of coolant with these nozzles.

Tubing and Tube Fittings

Barbed Fittings for Plastic and
Rubber Tubing—Chemicals

Fittings have a barb that grips onto tubing. Use in applications up to 120 psi.

Nuts for 37° Flared Fittings for Aluminum Tubing

Sleeves for 37° Flared Fittings for Aluminum Tubing

Pipe and Pipe Fittings

Right-Angle Flow Rectangular Manifolds

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.

Straight-Flow Rectangular Manifolds

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

Round Manifolds for Hose Lines

Mount these manifolds on the end of a hose line to distribute air, water, or hydraulic fluid to three locations from a single supply source.

Low-Profile Hex Manifolds

When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air or fluid to five locations from a single supply source.

Low-Profile Square Manifolds

With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air or fluid to three locations from a single supply source.

Straight-Flow Junction Blocks

Use these junction blocks to organize and separate multiple lines in your system. They have threaded holes that allow air or fluid to flow straight through the block.

Coolant Nozzles

Machine-Mount Coolant Nozzles
with Threaded Connection

These nozzles handle coolant pressure up to 150 psi.

High-Pressure Machine-Mount Coolant
Nozzles with Threaded Connection

For use in the highest pressure coolant lines, these nozzles are rated for at least 1,000 psi.

Adjustable-Spray Machine-Mount Coolant
Nozzles with Threaded Connection

The most versatile of our machine-mount coolant nozzles, these adjust from a fine mist to a direct stream and can deliver coolant in any direction. Max. pressure is 100 psi.

High-Pressure Machine-Mount Coolant
Nozzles with Ball-Socket Connection

For high-pressure coolant lines, these nozzles withstand pressure up to 500 psi.

Machine-Mount Coolant Nozzles
with Ball-Socket Connection

These nozzles handle coolant pressure up to 150 psi.
