Wear-, Impact-, and Chemical-Resistant PTFE Rods

Color: See table
Temperature Range: -400° to 550° F
Tensile Strength: 2,000-3,100 psi (Poor)
Impact Strength: 6 ft.-lbs./in. (Excellent)
Hardness: Not Rated (Medium)
For Use Outdoors: No
Specifications Met: See table

PTFE is modified with a filler material to create these impact-resistant rods. They have a super-slippery surface that resist wear, as well as excellent resistance to chemicals and extreme temperatures. These easy-to-machine rods are nonabsorbent, so they won’t swell when exposed to water. They’re also good electrical insulators.

Grade 641 is often used to fabricate bearings and pump parts.

Grade J is the most slippery of the Rulon materials and is often used to make gaskets and wear strips.

Grade LR is often used for sleeve, flange, and linear bearings.

Durable Glass-Filled Chemical-Resistant Slippery PTFE Rods

Color: Off-White
Temperature Range: -350° to 500° F
Tensile Strength: 1,000-2,500 psi (Poor)
Impact Strength: Not Rated
Hardness: Durometer 55D-66D (Medium Soft)
For Use Outdoors: Yes
Specifications Met: FDA Compliant 21 CFR 177.1550, UL 94 V-0

Made from glass-filled PTFE, these rods are more rigid and durable than standard PTFE rods. The reinforcement also prevents them from expanding when exposed to water and heat, so you can machine them to close tolerances. Use them in high-stress applications where resistance to chemicals and extreme temperatures is essential. They have a naturally slippery surface that resists sticking.

Durable Glass-Filled Chemical-Resistant Slippery PTFE Tubes

Color: Off-White
Temperature Range: -350° to 500° F
Tensile Strength: 1,000-2,500 psi (Poor)
Impact Strength: Not Rated
Hardness: Durometer 55D-66D (Medium Soft)
For Use Outdoors: Yes
Specifications Met: UL 94 V-0

For increased rigidity and durability over standard PTFE tubes, choose these glass-filled PTFE tubes. They offer the same naturally slippery surface that you’d expect from PTFE, along with the excellent resistance to chemicals and extreme temperatures. They can be machined to close tolerances because the reinforcement prevents them from expanding when exposed to water and heat. The OD is oversized and the ID is undersized for finishing to the sizes listed.
