Questions about the cover caps
Q
What are these cover caps for?
They cover the metal bleed and blanking plugs on a radiator or towel rail, so the ends finish in white instead of showing bare metal.
Q
Will they fit my radiator?
They suit plain metal blanking plugs and manual bleed plugs. They are not compatible with a plug that has a white plastic insert (as in the chart on this page). Measure your plug first: the cap's inside diameter is 24mm.
Q
What size are the caps?
Inside diameter 24mm, outside diameter 28mm, inside depth 6.6mm, overall height 8.6mm and a 2mm side wall.
Q
How many are in the pack?
One pair: 2 white cover caps, enough to cover two plugs.
Q
Do the caps come with the plugs?
No. This is the cap only. It does not include a bleed valve or blanking plugs.
Q
How do I fit them?
Press the cap onto the bleed or blanking plug by hand. No tools are needed.
Q
What are the caps made of?
Strong ABS plastic, which is durable and suited to humid bathroom conditions.
Q
Do they come in other colours?
Q
Are they valve covers?
No. These cover the bleed and blanking plugs only. They do not cover thermostatic or manual valve heads.
Q
How do I keep them clean?
Wipe with a soft damp cloth. Avoid harsh cleaners so the finish lasts.
