1" Conical Polyethylene Plug

The L.H. DOTTIE RD3DD is a conical plug made from polyethylene, sized at one inch length for sealing pipe ends or fittings. It suits plumbers and maintenance workers needing a simple, chemical-resistant closure for low-pressure lines.

Capacity and headroom

The tapered shape allows insertion into a range of internal diameters, providing a friction seal for temporary tests or permanent blanking. Polyethylene resists many common fluids but will deform under sustained high pressure or elevated temperature beyond its material limits.

Proposition 65 notice

California Proposition 65 warnings indicate the product contains a chemical known to the state to cause cancer and birth defects or other reproductive harm. This disclosure informs safe handling and disposal decisions for users in regulated environments.

Questions about this item

Will the 1" L polyethylene plug fit the existing copper pipe I plan to keep?

The plug is sized at 1" L and made from polyethylene; verify your pipe's nominal size and thread type before installation.

How can I confirm the RD3DD conical plug is sealing correctly after I install it?

Pressurise the line and check for leaks at the joint; a proper seal shows no moisture or pressure drop.

Does the RD3DD plug come with any gaskets or thread sealant, or must I buy them separately?

The supplied item is the conical plug only; any gaskets, tape or sealant required for your pipe must be sourced separately.
