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.

Abrasion-Resistant Sleeving

Tightly braided nylon fibers give this sleeving excellent abrasion resistance. As it wears, the fibers frizz and make the outer wall thicker for improved protection. The interior is smooth to reduce snags during installation. It meets Mine Safety and Health Administration (MSHA) standards for fire protection in mines. Because this sleeving is non-expandable, it does not stretch, so it’s best for applications where you know the exact diameter of the items you need to protect.

High-Strength Sleeving

This sleeving has excellent tear resistance and better abrasion resistance than standard polyester sleeving. Made of Nomex fabric, it resists most acids and alkalies, alcohol, hydraulic fluid, oil, gasoline, salt water, and solvents. It won’t irritate skin like fiberglass, so it’s easier to handle. Because this sleeving is non-expandable, it does not stretch, so it’s best for applications where you know the exact diameter of the items you need to protect.

Ultra-Insulating Low-Temperature Polyisocyanurate Foam Pipe Insulation

This very rigid insulation offers the lowest heat-flow rate of our pipe insulation and restricts absorption of water, air, and gas. It is typically used in process piping and chiller plants and performs best in applications below 50° F. To use outdoors, add metal jacketing.

Tubes have a kraft paper all-service jacket (ASJ) that resists mold and mildew by allowing moisture to evaporate. They have an adhesive strip closure.
