Stripped thread on Karcher

[MoodySabre]

My son has stripped the plastic thread on the pressurised side of his Karcher on to which screws the hose and pistol which has a metal fitting. I can't think what to do with it short of gluing it on there permanently and then what with?

Any ideas very welcome.

Kids - who'd have 'em

Sorry, I can't help but I've got one of those washers and it does strike me that that part is a poor design. It's almost as if they want people to do what your son has done.

Do Karcher do spares?

Yes they do but I suspect that you will have to buy a complete hose.....

Went through this a while back when a mate's Kaarcher went wrong. Unlike the high street stores which only sell the complete product, he found an outlet that dealt in the reconditioned seconds and also repaired them. Picked up the damaged housing for reasonable cost. Because of the pressures involved, I think you will need to replace the part of the pump housing with the threaded spigot on it. Of course, gluing it on may work, but if it fails you're likely to need a new hose too!

Unfortunately the part OP is talking about is the spigot which the hose fits onto, not the hose itself.

(Third try)........ If it is not polyethylene or polypropylene - Plastex (Ebay or online) will certainly weld it or you may be able to repair the thread with it.

For what it's worth (and, I apologise, not of much help to the OP) I'm on my second Karcher washer, and the joint in question has always given me problems - either I can't undo it without using pliers (and mashing up the grip on the collar) or I cross-thread it when attaching the hose. I've found that some vaseline or similar on the o-ring and threads before assembly works a treat - that, and undoing it immediately after use.

That's exactly what I do, but with silicone (or is it "silicon"?) grease.

MoodySabre,

if you do end up gluing it I'd think Sikaflex a better bet than most, though it would be a shame to open a new tube for a small amount like that; I'm sure someone here has a good tip on preventing it going off in the tube ?

Must be worth contacting Karcher direct.

I threw a broken Karcher out the other week, but still have the hose and lance bits. If they are any use you're welcome to them - they're no good to me.
Ps they're in Sussex, not too far from the M25

Thanks all. Looking at this site it looks like the pump head unit which at £62 + is not worth it. I feel a bodge coming on - followed by a new washer.
