OK, I'll try. All three products are similar when used in electrical connections.
First, TefGel and Gardner Bender Ox Guard anti oxidation compound work similarly from a physical standpoint. They both fill voids and are displaced by crimping or contact leaving a thin layer on the parts. The difference is that TefGel is PTFE and is more geared towards corrosion prevention. The GB compound has zinc and graphite and is more geared to preventing oxidation and promoting conductivity. While it may seem that coating a connection with PTFE would reduce conductivity, I've not seen it. I've not observed any significant resistance or voltage drop across any connector I've made using TefGel. I measured resistance under no-load condition. I also measured voltage drop across the connector while under load. It was a 3.5 gpm Shurflo freshwater pump happily pumping full blast. I used a Fluke 85 III multimeter which is a professional grade meter. Ass I recall, dielectric grease is primarily silicone based. You can buy it at auto parts stores made by Permatex. Physical action is that same. Fills voids and prevents intrusions. I've used it on electronics connections before but dropped it in favor of TefGel. I'll bet many a shade tree mechanic uses it in automotive service. The added advantage of TefGel is its anti-corrosion properties. It's lauded far and wide for use in preventing dissimilar metal corrosion. Tapping a stainless fastener into an aluminum rig? Coat it with TefGel! I've been using it for nearly 15 years now. My colleague here on "de bayou" has been using it much longer. Neither of us can remember a failure on any electrical connection we've made using TefGel. That's 25-30 years of crimping! Read TefGel's online reviews. Many of them say it was recommended by a marine industry person. While I think you could use any of the three types of product, my money's on TefGel. Dennis C.
