Nylon Polyester Expandable Braided Sleeve
E-FLEX® PET+PA Automotive Braided Wire Sleeve is a high-performance protective loom specifically engineered for demanding automotive and industrial environments. By blending the thermal stability of Flame-Retardant Polyester (PET) with the exceptional toughness of Nylon 6.6 (PA66) monofilaments, this sleeving delivers a superior shield against extreme abrasion, scuffing, and mechanical wear.
Designed to exceed rigorous automotive standards such as GMW14327 and ISO 6722-1 Class 6, it provides an armored yet lightweight layer for critical wire harnesses and hoses. Its open-weave construction expands up to 150%, ensuring a snug, flexible fit over connectors and tight bends while resisting gasoline, engine fluids, and UV degradation.

FAQ:
Q1: Why choose a nylon-polyester mix instead of PET only?
A: Nylon (PA66) provides much greater abrasion resistance than PET alone, making it more suitable for high-wear environments like engine bays or moving cable systems.
Q2: Can this sleeve handle sharp bends or corners?
A: Yes. The flexible woven structure allows it to conform smoothly to tight bends and uneven shapes.
Q3: Does it fray when cut?
A: If cut with scissors, yes. We recommend using a hot knife to seal the ends and prevent fraying.
Q4: Is this product fire-resistant?
A: Yes. It conforms to FMVSS 302 flammability standards with a combustion rate of less than 100mm/min.
Q5: Can I request customized sizes or packaging?
A: Absolutely. We offer custom diameters, colors, and roll lengths. Reach out to us with your specific requirements.
