Ether-Type Polyurethane Tubing

Outstanding abrasion resistance and flexibility for high purity applications

Ether-type urethane (PUR) tubing offers an outstanding balance of abrasion resistance and flexibility. It is used in high-purity and pneumatic applications that require more flexibility than LDPE tubing. This clear, tough, tear resistant tubing complies with FDA CFR 21 for food packaging.

Ether-PUR FLEX™ 84 (clear)– for high purity applications. Complies with FDA CFR 21 for food packaging. Ether-PUR FLEX™ 84 has an outstanding balance of abrasion resistance and flexibility.
