PATIKIL M25 Rubber Flat Washer, 10 Pack 25mm ID 39mm OD 2.5mm Thick Sealing Spacer Gasket Ring for Faucet Pipe Water Hose Fastener Bolt, Black

Good quality

A number of washers to allow sealing of valves in cistern

does the job expected - in my case seals for two waterbutt taps

I have no idea why I bought these !!!Water buttsThey work - I may have to buy more

bought this for 15mm flexible hose too big not right fit, would have sent it back but packaging was rip by myself

As described, arrived next day

but they don't look or feel or smell like rubber, very rigid and more like plastic.

I needed a replacement washer for a water butt tap and in the past I’ve just bought another tap as they’re not expensive. This time I thought I’d see if the washers were available separately. Bought this pack and they’re perfect for the job and much cheaper.
