Zipties- does it matter what product

[inktomi]

I've been using LaceLok on my build. It's nice; it doesn't require any knot knowledge and just works. It's rated up to 260°C. There are a few places I am still going to use a zip tie though - you just can't fit the lacelok gun in all the places you'd like to secure wire.

I do the same. In high school science, i was taught that the harder material will wear into the softer material. First crankshaft I pulled, i found a deep gouge in the crank where the rubber seal rides. No wear on the seal. Thought to myself i need to find that science teacher.

Your teacher wasn't wrong. The rubber seal is there to keep fine particles of... harder material... from passing through the seal. Those particles build up over time and do exactly what you saw.

I have been around many Pitts S2B rebuilds. Aviat always uses PVC electrical tape around any tube before putting a ty-wrap on. The explanation is; it will prevent the Ty-wrap from eventually cutting into the tube.

I don't prefer the PVC tape, and especially gummy residue. If I need something under the rubber of an Adel style clamp for example, I'll snip a strip of material off some SCAT tube. It is thin, grips smooth surfaces like pushrod tubes and engine mounts, stands up to heat and oil, and more importantly doesn't leave gummy residue.

Give Silicone Rescue Tape a try. I agree with you on PVC electrical tap - leaves a gummy residue, great for shop use or taping house electrical wires, but not for aviation (if I can avoid it). The Rescue Tape binds to itself through some sort of magic - bags great wraps around engine mount tubes and is very durable. If I have to wrap a Zip-Tie around a tube, and I don’t have a Grip-Lock, I always use the Rescue Tape.

I am ignorant and have only learned from search.

I need to change a CHT probe. There seem to be normal tipties used to secure these together, behind the baffles though. Is this acceptable?

I am reading that Tefzel have higher temperature tolerances.

Spruce sells some GripLock ties with rubber innards that they say can help decrease vibration.

I am only asking for opinion on using these for this application but need to learn about elsewhere.

What should I use and why?

I like GripLock ties, owned by Mike Patey of Scrappy STOL aircraft fame.
