Coolant Pipe

Nov 04, 2003 4 Replies

All our machines have the plastic Snap Lock type coolant pipe. Its a pain as when you put parts in the chuck its easy to knock it off the work. Also its a nuisance to make fine adjustments especially when running slow flow, coolant seems to walk around the nozzle moving off the work.



I found an old brass coolant pipe - came of an old Ward I think. Has two 90 degree elbows, and the spout is telescopic bent about 30 degrees at the end, can be adjusted to any angle, and is solid enough not to move if knocked.



Are these still made? I doubt it. Tried small bore pipe, 90 degree elbows and olives, if you loosen the joints the olives leak. On the old coolant pipe the brass elbows can be loosened to the tightness you need to move and they don't leak Cannot get them apart, undo the nuts but they won't come apart, must be some burs inside with over-tightening through the years. Have a feeling there is a felt washer inside?



Anyone know how they work?

Lionel Use your 90 degree elbows but replace the olive with a couple of O rings. You might ned to put two in, tighten it up , slacken off and cram another one in. You used to be able to buy some hard rubber olives at one time for Perkins fuel lines. I'll swear all they were was a piece cut dead square off a length of rubber pipe with a stanley knife. Once they had been tighten in and formed to the threads the ba#%^$d's would never come out.

I remember those rubber olives John, used to work for BRS in the early

70's. Completely forgot until you just mentioned them.

Thanks

John's memory serves him well, as usual. They are more easily acquired as a CAV part rather than finding a Perkins dealership.

Strangely, some makers used metal olives on their duel systems while Perkins went for the cylindrical plastic/neoprene type. 4-235 and 6-354 used them, the smaller ones didn't IIRC.

Vince across the road from us has probably got some, want me to ask him in the morning ??
