Brass Caps and Plugs Pipe Fittings

Brass caps and plugs close unused threaded outlets and pipe ends on water, air and gas lines.

Caps close male threads and plugs close female outlets. Both can be removed later.

What are brass caps and plugs?

Brass pipe fittings are threaded brass parts that join, turn, branch, reduce and close small pipes and equipment connections. The range includes elbows, tees, sockets, nipples, bushes, unions, adapters, caps and plugs.

Brass is used because it does not rust, machines precisely and suits water, air and gas. Therefore, brass fittings appear at taps, meters, valves, gauges and LPG regulators.

Key terms explained

Brass: An alloy of copper and zinc. It resists corrosion, machines cleanly and makes precise threads.
BSP thread: British Standard Pipe thread, the common pipe thread in Kenya. Taper threads (BSPT) seal as they tighten.
Dezincification: Slow loss of zinc from some brasses in aggressive water, which weakens the metal. DZR brass resists it.
Male and female thread: A male thread is on the outside of a part. A female thread is on the inside.
Union: A three-part fitting that lets a joint be opened without turning the pipes.
Adapter: A fitting that changes thread type, size or pipe system.
