Overview

The **Woodhead 36501 Dust-Tight Strain Relief** is a heavy-duty industrial strain relief designed to secure and protect cables in demanding environments. Engineered for **1/2" NPT straight male thread** installations, this strain relief delivers a **dust-tight seal** (IP6X implied) and **NEMA 12** compliance, making it ideal for use in control panels, machinery wiring, and electrical enclosures. The **5.59–8.13mm (.220–.320") cable diameter range** accommodates a wide variety of flexible cords, while the **galvanized steel mesh collar** and **zinc-plated steel nut** provide exceptional mechanical durability with a **300 lbs (136.08 kg) break strength** to prevent cable pull-out in high-vibration or high-tension applications. Constructed with an **aluminum threaded body**, **neoprene dust seal gasket**, and **thermoplastic insulated bushing**, the 36501 ensures long-term performance in harsh industrial settings. The **single-weave mesh design** offers flexibility without compromising grip strength, making it suitable for dynamic applications where cables experience frequent movement or bending. Its **3.25" mesh length** and **black grommet** provide easy identification and installation. Certified to **UL File No. E76954** and **CSA File No. LR32159**, the Woodhead 36501 meets North American safety standards for use in **Class I, Division 2; Class II, Divisions 1 & 2; and Class III, Divisions 1 & 2** hazardous locations. The strain relief is also suitable for **NEMA 4** wet locations when paired with a gasket between the fitting and enclosure. Industries benefiting from the 36501 include **manufacturing, automation, HVAC, robotics, and heavy machinery**, where cable integrity is critical to operational safety and efficiency. For applications requiring a **dust-tight seal, high break strength, and versatile cable compatibility**, the Woodhead 36501 stands out as a reliable and cost-effective solution. Its **compact design** and **replacement grommet option (Order No. 130180-0403)** ensure long-term maintainability, reducing downtime and maintenance costs.
