Metal Barbed Hose Fittings for Air and Water
Slide the barbed end into rubber hose and secure with the appropriate clamp or crimp-on hose ferrule.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. Plain brass fittings have good corrosion resistance. Nickel-plated brass fittings resist corrosion better than plain brass fittings.
Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance.
Stainless steel fittings have very good corrosion resistance. 303 stainless steel fittings won’t rust when exposed to water, making them good for areas that require frequent cleanings. Fittings with a threaded end are also known as hose nipples.
Hose connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose.
Metric, UN/UNF (SAE Straight), and BSPP male threads with gasket protect against leaks.

High-Pressure Hard Plastic Tubing for Air and Water
Excellent strength and durability allow this tubing to handle high-pressure air and water applications.
Polycarbonate tubing won’t degrade when exposed to the damaging effects of ultraviolet light. It should be used at temperatures above freezing. Tubing is clear, so you can easily monitor flow. It is rigid and does not bend.

Abrasion-Resistant Firm Rubber Tubing for Air and Water

With excellent resistance to abrasion and tearing, this rubber tubing can hold up in rugged environments. It is semi-flexible, so it is good for gradual bends.
Neoprene tubing can handle higher temperatures than polyurethane tubing. It meets ASTM E162 specifications for surface flammability. Tubing is opaque, so you cannot see what’s running through the line.
UV-Resistant Firm Plastic Tubing for Air and Water

- Flexible
- Compatible with Barbed Tube Fittings
- Firm (Durometer 85A)
- Temperature Range: -10° to 220° F
With a unique combination of UV resistance and clarity, this PVC tubing won’t degrade from the damaging effects of ultraviolet light exposure, and allows you to monitor flow through the line. Tubing is flexible, so it can easily bend around objects.
Soft Plastic Tubing for Air and Water

This general purpose PVC tubing is the industry standard for air and water applications. Tubing is clear, so you can easily monitor flow. It is flexible to easily bend around objects.
Masterkleer tubing is more economical than Tygon tubing. Tygon tubing has a nonabsorbing surface for improved flow and drainage.
Tubing that meets NSF/ANSI 51 is safe for contact with food and beverage.
- Flexible
- Compatible with Barbed Tube Fittings
- Soft (Durometer 65A)
- Temperature Range: -30° to 160° F
Choose-a-Color Soft Plastic Tubing for Air and Water





To identify lines at a glance, use different colored tubing as a color code. Tubing is clear, with either a colored tint or a colored stripe, so you can see what’s flowing through the line. Made of PVC, it is the industry standard for air and water applications. Tubing is flexible to easily bend around objects.
FB70-PVC tubing resists odor and taste transfer.
Tubing that is FDA compliant and meets NSF/ANSI 51 is safe for contact with food and beverages.
- Flexible
- Compatible with Barbed Tube Fittings
- Soft (Durometer 70A)

UV-Resistant Soft Plastic and Rubber Tubing for Air and Water

This tubing won’t degrade when exposed to the damaging effects of ultraviolet light. It is opaque, so you can’t see what’s flowing through the line.
EPDM rubber tubing is the most flexible option. It has better durability than PVC tubing to stand up to harsh outdoor environments. It has excellent resistance to ozone as well as UV light.
High-Temperature Soft Rubber Tubing for Air and Water







- Flexible
- Compatible with Barbed Tube Fittings
- Soft
- Temperature Range: -90° to 390° F
More resilient than latex rubber, this silicone rubber tubing can stand up to high-temperature applications. Commonly used with metering (peristaltic) pumps and robotics, it can handle continuous bending and flexing and maintains its flexibility over time.
Opaque tubing doesn’t allow you to see what’s flowing through the line. Semi-clear tubing gives you a limited view inside the line.
Continuous-Flex Soft Plastic Tubing for Air and Water

This PVC tubing can handle continuous bending and flexing in applications requiring movement, such as metering (peristaltic) pumps and robotics. Tubing is clear, so you can easily monitor flow through the line. It’s commonly referred to as Tygon tubing.
Flame-Retardant Soft Rubber Tubing for Air and Water

- Flexible
- Compatible with Barbed Tube Fittings
- Soft (Durometer 60A)
- Temperature Range: -70° to 450° F
This self-extinguishing, silicone rubber tubing meets UL 94 V-0 and UL 94 V-1 for flame retardance, so it delays the spread of flames to valuable equipment. It is opaque, so you cannot see what’s flowing through the line. Tubing is flexible to easily bend around objects.
Smooth-Bore Seamless Stainless Steel Tubing

Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.
316 stainless steel offers excellent corrosion resistance.
Tubing that meets ASTM specifications adheres to international standards for dimensions and materials.
- Temperature Range: -325° to 1500° F
- Bending Method: Tube Bender
- For Use With: Hydraulic Fluid, Oil, Water, Natural Gas, Air
- Compatible Tubing Fittings: see table
Welded Stainless Steel Tubing

When your application does not require a smooth interior, this tubing is an economical choice. It has a weld bead on the inside.
304 stainless steel has very good corrosion resistance.
316 stainless steel offers excellent corrosion resistance.
- Temperature Range: -420° to 600° F
- Bending Method: Tube Bender
Brass Tubing

Frequently used in a wide range of plumbing applications, this tubing holds up well in mildly corrosive environments. Tubing is seamless, so it has a smooth interior for unrestricted flow.
Smooth-Bore Seamless Steel Tubing

Seamless construction with no weld bead gives this tubing a smooth interior for unrestricted flow. It is stronger than welded tubing and can be flared without splitting. Do not use in corrosive environments.
