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.

Fiberglass Pipe Insulation

This common insulation material is typically used on hot and cold water lines and in process piping. To use outdoors, add metal jacketing.

Tubes, elbows, and tees are formed to provide the best fit on pipe and are the easiest to install. If your pipe is larger than the sizes we offer, choose a sheet/strip.

Tubes have an all-service jacket (ASJ) made of kraft paper with an adhesive strip closure. Seal with reinforced insulation tape (sold separately).

Elbows and tees with PVC jacketing seal using reinforced HVAC tape (sold separately).
