Woodhead 67-0300 Closure Cap 1 Inch 14 Tpi IP67

Product Description

The WOODHEAD 67-0300 is a male internal thread receptacle closure cap designed to protect industrial electrical receptacles from dust, moisture, and contaminants. The cap features a 1-inch diameter opening with a 14 threads-per-inch (TPI) internal thread pattern, rated IP67 for full dust exclusion and protection against water immersion from approximately 6 inches to 39 inches of depth. A captive ringlet keeps the cap attached to the receptacle body during removal, preventing loss in the field. Licensed electricians and automation maintenance technicians install this accessory as part of connector protection in industrial environments.

This closure cap is used in industrial automation, manufacturing, and harsh-environment electrical installations where receptacles must remain protected when disconnected. The IP67 rating makes it suitable for applications subject to washdown, heavy dust, or intermittent immersion. It is commonly installed on Brad Harrison-style receptacles used in automation infrastructure wiring, including connections for power distribution and industrial network equipment in production facilities.

Installation Notes

Installation and replacement should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the circuit and verify the receptacle is fully unpowered before removing or installing the closure cap. Thread the cap fully by hand until seated to ensure the IP67 seal is maintained. Do not use tools to overtighten, as damage to the thread or sealing surface may compromise the environmental rating.
