DOT 5 Silicone brake fluid is combatable with both types of seals i.e.
Buna-N-(Nitrile) and Ethylene-Proplene,
DOT 3/4/5.1 (five point one) is glycol based and should only be used with
Ethylene- Proplene seals.
The Automotive seals SP2044 and SP3694 are made of Ethylene-Proplene , So
DOT3/4/5.1 (five point one) Or Silicone DOT 5 (five) is acceptable.
MATCO Brake caliper Seals are made of Buna-N-Nitrile and will use MIL-H5606
hydraulic fluid Or ATF automatic transmission fluid OR DOT5 (five)Silicone
fluid
Your choice is to CHANGE ALL YOUR SEALS TO Ethylene-Proplene and use Glycol
based DOT 3/4/5.1(five point one) THE PREFERRED OPTION IMHO, THAT'S WHAT I
HAVE DONE USING GLYCOL DOT 5.1 (FIVE POINT ONE) Or use Silicone DOT
5(FIVE)
OR CHANGE ALL YOUR SEALS TO Buna-N(Nitrile) which will use MIL-H5606 or ATF
automatic transmission fluid or Silicone DOT 5 (five)
HAVE A MIXTURE OF BOTH TYPES OF SEALS IN THE ONE SYSTEM MEANS YOU MUST USE
SILICONE DOT 5 (FIVE)
I hope that clears the misunderstanding

compatible only with Dot5. Now you imply that they are for automotive fluid,
i.e. Dot3 etc.. Please confirm one way or the other, and where does ATF fit
in ?
