Coolant pipe seals

Hi everyone,

I have recently brought a coolant pipe (epay) for my lathe, so I can replace the leaking plastic thing I have. I need to replace the seals on the elbow joints but for the life of me i can't seem to find any where to buy them?

Would any one be able to offer any help please?

Coolant pipes and other accessories on lathes are not universal. It would help to know your lathe's make and model for a forum member to be able to help, from experience with lathes of the same make and model.

If the elbow seals are o-rings you can get them at any seal or bearing supply house, or the Bay of E. If you get seals made of Viton elastomer ( rather than the more common neoprene rubber ones) they are extremely chemical resistant and will take high temps (if placed too near a lamp for example) on a machine.

Hi George any information and pictures would help as to what seems you need.

Hi George,

I take it the gland nut butts against the steel shoulder and then the brass insert fits into the elbow bore? I have seen some connections like this with a gland nut having an o-ring on the groove at the steel/brass joint area and a plastic (normally PEEK) back-up ring to allow actual tightening of the joint and compresion of the o-ring whilst allowing flexibility in the joint. The back-up rings would be a plastic ring with a split to allow it to be pusted on to an oversize OD and then set inside a groove - would be easy to turn from some durable plastic and then form a scarf joint with a sharp knife blade. Make a pair of backup rings and use an o-ring that will crease a good sealing fit on the OD of the pipe and the bore of the elbow I hope this makes sense?
