    Hi all,

    I am looking for a place to buy Radiator Valve Caps.

    Picture 1: Got 1 radiators with no caps
    Picture 2: Got 4 radiators with this cap
    Picture 3: Got 3 radiators with this cap
    Picture 4: No cap but the pin is different size compared to picture 1

    Picture 1, each pin is 15mm high and 6mm thick at the top
    Picture 4, pin is 10mm high and 6mm thick at the top

    On each radiator i also have a Drayton TRV4

    I am just looking to replace each one so there is some uniformity, right now it's all over the place:eek:

    Preferably chrome ones if possible, if not than white ones.

    Any ideas?

    All the best

    Thanks Riley, i have found a online website that sells them in packs of 10, due to me not being able to drive it's cheaper for me to buy online.

    It’s very important to make sure rad valve caps are fitted, little people can fall small heads fit into corner between wall and rad. Brass head then penetrates child forehead ouch ! My surveyed friend fails rentals for letting if rad caps are missing for this reason. Rob Foster centralheatking

    First 3 photos are of Peglers Terrier older type valves.
    I actually have some spare used heads for them, lockshield and wheel head.
    The forth valve is one of the standard cheap valves
    You can also get sets of universal heads that might sort it.
