Conical Plug for Conduit Sealing

The L.H. DOTTIE RD2HXTP is a polyethylene conical plug designed to seal 1-inch conduit openings. It suits electricians and maintenance crews who need a friction-fit closure during installation or long-term protection. The plug prevents debris and moisture from entering raceways. It is not for buyers who need a threaded or lockable seal.

Behaviour Under Sustained Load

Polyethylene resists compression set when left in place for extended periods. The tapered profile maintains a tight seal against vibration and thermal cycling. The material does not degrade from contact with common cable-pulling lubricants. It is not for applications that require a pressure-rated barrier.

Thermal and Chemical Resistance

The plug withstands typical job-site temperature swings without cracking or softening. Polyethylene is inert to most oils and solvents encountered in electrical work. California Proposition 65 warnings apply because the material contains a listed chemical. Orders of $75 or more ship free from the manufacturer.

Questions about this item

Does the RD2HXTP conical plug generate any heat or noise when left in place continuously?

The plug is a passive polyethylene fitting with no moving parts or electrical components, so it produces no heat and makes no sound during long-term use.

What conduit or fitting must I already have for this 1-inch conical plug to seal properly?

It is designed to press into a 1-inch conduit opening or hub, so you need a matching 1-inch conduit or fitting with an internal diameter that accepts a tapered plug.

Will this polyethylene plug become brittle or react when used alongside older metal conduit and fittings?

Polyethylene resists corrosion and does not conduct electricity, so it will not degrade or cause galvanic issues when installed next to aged metal conduit components.
