I need to cap some hard lines, and I can't seem to find anywhere that sells silicone caps. I can find the cheapo kind at the auto store, but those get brittle and crack pretty easy.

Any ideas? I'm looking for the standard size (3.5mm)
Thanks -

 

Good question

Search for "silicone cap." They also have some EPDM rubber caps that work great (much better than those crappy auto-store kind).

I dont see any silicon caps there in a size that'll work for our application all that well. As mentioned, standard size for us is 3.5mm which comes out to .150" or so. I find that 5/32", or .156", hose and caps work well, and are in fact a bit tight which is probably a good thing. They only list sizes in .125 which is way too small or .172 which is somewhat too big.

Now in the epdm caps, those sizes look about right.

 

The EPDM's work perfectly, and are what I use on all my motors. Some people are just against using "rubber" though. For them, the 0.125" silicone caps work just fine too.

perfect! EPDMs on order - thanks guys.

off topic...
RotaryResurrection - are those ASA AR1s on your car? If so, are you running 18x8s or 18x9s? do the 265s have any fitment issues?

 

No, these are the dreaded (by some of the elite mclaren-driving forum members, anyway) adr msports. They are 18x8.5 and 9.5 with 235s and 265s (room for 275s). No rubbing at all in back, very slight rubbing when cutting the wheel in a parking lot (rubs inner fender well) or when cornering very hard (stock suspension allows too much travel).

 

ahh, ok - cool. they look good -
