We’re excited to announce the launch of a new addition to our cable protection lineup: the Heyco® Cordgrip with Integral Sealing Ring. Engineered for reliability in harsh environments, this innovative cordgrip offers an advanced sealing solution to meet your toughest application demands.
A Smarter Seal – Built In
What sets this new cordgrip apart? The integral sealing ring. Unlike traditional options, this built-in feature ensures a consistent and secure seal at the clearance or threaded mounting hole every time—enhancing protection and reducing assembly errors.
Features & Benefits
- IP68 Rated: Offers complete protection against dust and extended water immersion.
- NEMA Approved: Suitable for NEMA 4, 4X, 6, and 6P applications, making it ideal for both indoor and outdoor environments.
- Superior Seal: The integral sealing ring provides consistent sealing performance—every time.
- Wide Cable Range: Accommodates flexible cord diameters from 0.065” (1.7 mm) to 1.730” (44.0 mm), offering a broad sealing range.
- Anti-Vibration Design: Ratchet-style sealing nut ensures a firm grip and minimizes the risk of loosening due to vibration.
- Quick Installation: Acme threads on the body prevent skipping and make for fast, hassle-free assembly.
- Chemical Resistance: Constructed from Nylon 6/6 with Buna N or TPE sealing glands, these fittings resist salt water, oils, weak acids, alcohol, and common solvents.
