docc Posted June 21, 2023 Share Posted June 21, 2023 There are those of us who are such fans of what Caig DeOxit® does for connectivity across fuses, relays, switches, and connectors. Yet, as @PJPR01 recently pointed out, connector seals can swell and tear from DeOxit exposure. Specifically, the green Metri-Pack seal on the V11 TPS and the Casper's TPS Breakout Harness. But also the yellow TE AMP SuperSeal connectors in the rest of our wiring harness(es). See how this 5-position AMP connector seal swelled after exposure to DeOxit? Once the tank was back on, that connector was not connected and the tank had to come back off and the connector compressed with a clamp, then "zip-tied" to make connection . . . I plan on replacing the seals at next "tank off." Yet, the seals are not available separately. The TE/AMP connectors are available from various suppliers including Gregory Bender. Buy the connector, slip off the seal as a replacement. See the link, above, for sources of the TPS 3-position "Metri-Pack" connector/seal. Otherwise, be aware that while Caig DeOxit® is electron-magic, it will swell these seals and make them vulnerable to tear and possibly interfere with the connector reliably engaging/connecting. 3 1 Link to comment Share on other sites More sharing options...
docc Posted June 21, 2023 Author Share Posted June 21, 2023 Specific seal damage/tear on the Metri-Pack 3-position connector seal from my TPS next to a new seal (the damaged seal on my TPS Casper's Breakout Harness looks similar): 1 1 Link to comment Share on other sites More sharing options...
guzziart Posted June 21, 2023 Share Posted June 21, 2023 I wonder if a good used seal can be had from a junkyard since they been using those types of connectors on cars for the last 20+ years. And, I think I used the wrong type of de oxit on the rheostats of my 45yo Pioneer 1010. Link to comment Share on other sites More sharing options...

cowtownchemist Posted June 21, 2023 Share Posted June 21, 2023 DeOxit is great stuff on electronics but not really great on rubbers. 75% of its formulation is mineral spirits. https://caig.com/product/deoxit-d5s-6-lmh/ 1 Link to comment Share on other sites More sharing options...
cowtownchemist Posted June 21, 2023 Share Posted June 21, 2023 After a little bit of reading on their site, they do offer a non-flammable version which does not use mineral spirits and therefore will not swell rubber. 1 3 Link to comment Share on other sites More sharing options...
gstallons Posted June 21, 2023 Share Posted June 21, 2023 Hmmmm . I wonder what the manufacturers recommend on these connections ? 1 Link to comment Share on other sites More sharing options...
gstallons Posted June 21, 2023 Share Posted June 21, 2023 I Googled this question last night and came up with nothing . These connectors are in the AC delco / Packard family and I looked for compounds that could be used with them . Found nothing . I am sure these were intended to be installed dry but IDK what CAN be used w/them . I use the MC electrical grease on Deutch connectors only to make it easy to disconnect in the future . 1 Link to comment Share on other sites More sharing options...
Pressureangle Posted June 21, 2023 Share Posted June 21, 2023 You guys use spray deoxit? I have little tubes, setting a single drop directly on the contacts. I don't think I ever get enough on anything to get to the rubber- and just as a matter of habit (won by hard experience) I let everything dry for a couple minutes before I reassemble pretty much anything anywhere. Still, important information. 1 Link to comment Share on other sites More sharing options...

Hi Chuck, Yeah, I used their D5 stuff on the old stereo I didn't know there were different blends of Deoxit when I bought their D5 years ago Art Link to comment Share on other sites More sharing options...
