Cable gland washers provide critical sealing and vibration resistance for industrial cable entries. Engineered to maintain ingress protection (IP66, IP68, IP69K) across enclosures and machinery, our washers prevent moisture, dust, and chemical ingress in demanding operational environments. Available in standard and custom dimensions for Metric, PG, and NPT thread profiles, backed by ISO 9001 certified manufacturing and strict lot traceability.
Material Integrity:
Formulated from high-grade elastomer and metal compounds resistant to aging, UV exposure, and hydrocarbons.
Positive Sealing Structure:
Precision-molded profiles distribute clamping force evenly to eliminate leakage paths around the thread shank.
Vibration Dampening:
Absorbs mechanical shock, preventing cable glands from loosening under continuous machine vibration.
Thermal Stability:
Compounds engineered to maintain elasticity and sealing performance across wide temperature extremes.
Thread Standards: Metric (M12 to M63), PG (PG7 to PG48), NPT (1/4" to 2"), and G threads.
Material Options: EPDM, NBR (Nitrile), Silicone, Neoprene, PTFE, Nylon, and Stainless Steel (304/316).
Operating Temperature:
EPDM: -40°C to +120°C
Silicone: -60°C to +200°C
NBR: -30°C to +100°C
Ingress Protection: Up to IP68 (5 bar / 1 hour) and IP69K certified when paired with matched cable glands.
Compliance & Standards: ISO 9001 facility, RoHS, REACH, UL 94 V-0 (select silicone grades), and CE compliant.
Flat Washers vs. O-Rings:
Flat gaskets for face sealing against enclosure walls; O-rings for groove seating under gland entry threads.
