Small diameter plastic oil lines on mill - what sort of tube?
Looks like I need to replace one of the small oil lines on the knee of my TOS mill as its about 20mm too short to connect to the pump.
There's no pressure as such, just a few drops of oil every 5 seconds or so to lube the way.
Any idea what type the original tube might have been? Its 3mm ID, transparent, quite hard, and a brown colour. Possibly it was soft and clear when it was new.
I was thinking of just using clear flexible PVC tube to replace it unless anyone has a better suggestion.

Clear PVC is not really a long term material to use in this situation as it will go hard, loses flexibility fo it easily cracks and leaks. It can also react with some oils/lubes. The best tubing is silicone - it costs more but it stays flexible for a long time.

Hi Steve, Guys,
I use vinyl tube as replacement for the generator fuel lines ! Car window screen washers often use vinyl tube as well. Its much softer than PVC tube.
Actually I've just bought a 30 mtr roll of 6 mm bore 1 mm wall clear vinyl tube to make an oiler system for the lathe. It cost me £10 from the local garage. They also have the little crimp rings to suit it.Best Regards:

How about polyurethane tube used for pneumatic systems?

Thanks everyone.
I had a closer look last night at where the tube runs, and I’m not convinced it doesn’t have some form of retainer to keep it in place inside the casting.
There are other retainers that I can see in different areas that consist of what looks to be a blind pin inserted next to the tubes to hold them against the casting.
I don’t want to be forced into stripping the knee any more than I already have, so the safest thing at the moment is to make up a small barbed joiner and just add a short piece of tube to extend the existing one that’s too short.

You would not get something like that at you local garage in Aus any more, maybe if it was the early eighties, just fuel and groceries these days

Hi China,
Maybe caught by words having the same spelling but slightly different meanings
Here "Garage" implies a place that repairs and services cars and vans etc. While I think that you mean what we call a "Filling station".
As you suggest in the old days a "Garage" did everything from selling fuel, oils, parts, cigarettes, tyres and a host of things that you just don't find outside of a Supermarket.
How times have changed !Best Regards:

Pirtek?
Did one of the mills here several years ago - need to fix one line on another now too! The stuff I used was capillary tubing, it was black nylon(??). Trying to remember where I got it, might have been the local hydraulic place or VDO instruments, in this case, compression olives and screw-on fittings to the hardline.
