(H)DPX/HDKX Tubtara® with applied (chemical) seal under the head.
Several seal options are possible for our (H)DPX and HDKX series, depending on head shape and application requirements. For P (flat head) parts, we advise precote® 200 or Rimlex® 620B, or Rimlex® 310 for high temperature applications.
Our HDKX series with low profile head, feature a thin precote® 5 or 15 acrylate seal, but note that these require specific hole preparation to obtain a leakproof assembly (see below).
These seals are resistant to many automotive oils, antifreeze and transmission fluids, and ensure a leakproof assembly, if correctly installed. Technical data sheets are available on request.
Hole preparation for semi-hex HDKX + Precote® seal.
To obtain an IP x7 leakproof assembly with semi-hex (stainless steel) HDKX series, the hexagonal holes need to be formed with a radius:
