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.

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.

Crack-Resistant Firm Plastic Tubing for Food and Beverage

Semi-Clear Tubing

This tubing offers superior impact and crack resistance—even at low temperatures. Made of FDA listed materials, it is suitable for use with food and beverage. It is made without plasticizers like DEHP, so it won’t impart tastes or odors to the fluid passing through it. Tubing is semi-flexible, so it is good for gradual bends.

Polyethylene tubing can withstand lower temperatures and higher pressures than EVA tubing.

Semi-clear tubing gives you a limited view inside the line.

Hard Plastic Tubing for Food and Beverage

Strong, hard walls give this tubing extra support in high-pressure and vacuum applications. It’s made of FDA listed materials, so it’s suitable for use with food and beverage. Free of plasticizers like DEHP, it won’t impart tastes or odors to the fluid passing through it.

PVC tubing has harder walls than polyethylene tubing and can handle higher pressures. It meets NSF/ANSI Standard 51 for food contact. Tubing is rigid and will not bend. It is clear, so you can easily monitor flow.

Metal interlocked strips create a rigid, durable hose that stays strong under high temperatures. Hose is for use with smoke, welding fumes, and oil fumes.

Galvanized steel offers fair corrosion resistance.

304 stainless steel has very good corrosion resistance.
