Continuous-Flex Soft Rubber Tubing for Chemicals
- Flexible
- Compatible with Barbed Tube Fittings
- Hardness:
Inch: Soft (Durometer 65A)
Metric: Soft (Durometer 55A) - Temperature Range:
Inch: -70° to 245° F
Metric: -10° to 270° F
Commonly used in applications requiring movement, such as metering (peristaltic) pumps and robotics, this tubing can handle continuous bending and flexing. It has the chemical resistance to withstand a variety of acids and other harsh substances. Tubing is opaque, so you cannot see inside the line to monitor flow.

Continuous-Flex Soft Plastic and Rubber Tubing for Food and Beverage
- Flexible
- Compatible with Barbed Tube Fittings
- Soft (Durometer 70A)
- Temperature Range: -70° to 270° F
This TPV tubing is highly resilient and can stand up to repeated bending and flexing. It is typically used in applications requiring movement, such as metering (peristaltic) pumps and robotics. Tubing is suitable for use with food and beverage and doesn’t contain plasticizers like DEHP, so it won’t impart tastes or odors to the fluid passing through it. It is opaque, so you cannot see inside the line to monitor flow.

Screw-On Nut Barbed Tube Fittings for Air
(SAE Straight) Male
Threads with Gasket
- Temperature Range: 20° to 140° F
- Tubing: Fittings with Anodized Aluminum, Brass, or Nylon Plastic Material: Use with firm or hard (Durometer 95A-60D) polyethylene plastic or polyurethane rubber
Fittings with 316 Stainless Steel Material: Use with firm or hard (Durometer 80A-95A) nylon plastic, polyethylene plastic or polyurethane rubber
You don’t need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to hold the tubing in place.
Aluminum and nylon fittings have better corrosion resistance than brass and are lighter in weight.
Metric and BSPP male threads with gasket provide extra protection against leaks.
