I fired up the pressure washer this afternoon and the high-pressure outlet is leaking badly since the o-ring is shot.

Anyone know a Pattaya supplier of o-rings that may fit? It's a MAC brand machine from the UK but o-rings should be pretty generic.

Thanks,

Any decent truck/farm dealer should have something.

If you have no luck elsewhere try a dive shop. They may have one that fits or point you in the right direction where to buy one.

Up chaiyapruek 2 just before the railway crossing on the left side is a hardware store that has the sets of o rings in the blue plastic boxes I am sure you will be familiar with, one box imperial one metric, and they sell the rings individually.

That sounds like a good bet. Thanks.

That is a great bit of lateral thinking. They use o-rings all over the place so a good alternative. Thanks.

They are the same size rubber rings as all the push on water pipe connectors...... most hardware stores sell them, even the little shops, garden shops, Home pro sell in a pre pack of 4..

I use my pressure washer every other day and no problems, but others that use only 1 x a month have this problem.... I have 6 outside water taps all with the push on type water connectors the one tap not used that often the ring is always breaking,... maybe the rings when old dry out and break more easy ?

You are talking about the low-pressure inlet side and yes, those larger 5/8" (approx) o-rings are available.

The ones I am looking for are 3/8" (approx) for the high-pressure side of the washer.

Now, of you reckon HomePro does have the smaller ones, I will be down there like a shot.

Thanks!

A little silicone grease on the O-rings for long life..

Had no idea they were different, I use on both sides, no wonder they slip on easy..

have a small 100 bar Bosch machine and a big one 170 bar 250 watt which I use a lot. [2 - 3 hour per time constant use 4 x weeks]

So sorry cannot help, but would say more likely in a smaller private owned hardware store where they may have a collection of these rings in different sizes

Good point. I always purged the machine and lines of water after every use and if I get lucky with o-rings, I will start lubing them as well.

I have a box set if can contact me I can post u one for free, I need to know the id ,the od and also the diameter if posible of the rubber

If you urgently need to use the machine, wrap the area up with some ptfe tape. It will hold up while you search for the o-rings

somtam palah

What size do you need ?

Success!

Nice hardware store as well!

(They have decanted the o-rings into bins now so metric and imperial are mixed up but they had what I wanted; 4 sets of the four sizes required for 120 baht).

Update... one of the o-rings was too fat for the job so I popped into Santi Hardware opposite Foodland on Klang on the off-chance they had some o-rings and they do! Bit more expensive than the Chayapruek 2 shop but a lot nearer home.
