Subject: Brake Bleeder Caps
I've started making my own brake reservoir caps to sell with the pressure
bleeder kits. The AST TA18's were decent quality but a bit on the pricey
side. The less expensive Technic tool caps were poorly finished, had poorly
fitting gaskets and the inlet plugs were metric thread (required rethreading
to 1/4"NPT).
The new caps have been improved as follows: (1) 6061 T6 aluminum
construction (aircraft quality-same as the race jacks) with a deep red
(matte) anodized finish (2) special nitrile (Buna-N) gasket with an A-scale
shore hardness of 60 (durometer), 3/32" thickness. This appears to be the
best compromise for seal quality and durability. The factory gaskets are a
shore 50, 1/16" thick and would tear from repeated R&R (3) choice of 2
different 1/4" male inlet plugs....polished brass fixed connector or nickel
plated hardened steel ball-swivel connector. The polished brass unit is
aesthetically nicer but the ball swivel unit is better ergonomically (4)
optional pushbutton disconnect. This puts less stress on the reservoir when
disconnecting the supply hose. (5) optional diaphragm-type low pressure
regulator with gauge (for portable air tank usage or other non-regulated air
supply) (6) optional whip hose connector (air bleed systems only).
Anyone having purchased a cap from me in 1997 can take a $20.00 credit with
the return of their old cap against the $30.00 cost of a new one.
My thanks to all the digest folks for their support in 1997 and best wishes
to all for healthy, happy New Year. SD
