Brake pipe flaring

[hanloncole]

What size brake pipe is the std T25 is it 3/16 or 3/8 diameter?
Thanks

3/16 or 4 and a bit mm

Just say VW Transporter (year) to your friendly motafax man and he'll make it up in a jiff. If you can, take the old one for a him to scrute, or measure length.

non metric on a german vehicle? is there some brake pipe standard that never changed with decimalisation Clive?

[HarryMann]

Hehee!
No idea about brake pipes, but expect they all conform to either SAE or ISO standards and the old Brit systems, if there were any switched to SAE (US) around the war.

Once you've got a standard that works, and is accepted and everyone's tooled up for it, there would be abs. no point in changing it, even for he indubitably better metric system

3/16" hydraulic pipes have safe working pressures up to about 3,000 psi, 1/4" ones, just over 2,000 psi...

or would you rather me quote that in KPascals, so it rolls off the tongue a bit easier

As a reference these are the brake pipe parts :-

3/16" O.D. Short Male Nut M10 x 1mm (guide price ~ 24p)
3/16" O.D. Female Nut M10 x 1mm (guide price ~ 17p)
3/16" O.D. Female Connector M10 x 1mm (guide price ~ 80p)
3/16" O.D. Kunifer Brake Pipe (guide price ~ 95p/Mtr.)

All the pipes I have come across are single-flared,unless you know differently (Perhaps the little ones into the front calipers might be double flared ? I can't remember from last Feb.)

Cheers,Ian.

3/16 it is then

Did a few brake pipes on the trundletruck this year. Watch the rear ones that go across the van to the rear brakes, where they are attached!

All the flares are D.I.N double flares.

A tip I got was to use a joining block in the middle so it is easier to replace the front and rear pipes later.
