O Ring Material

[Robinda]

Just a quick one I have 2 Fenix LD 20 torches (I am in the UK) I use on my bike which are great. While I can find lots of info on what lube to use or not use on what O Ring material, how do you find out what they are made of.

I have always used petroleum jelly on my old Maglights which never bothered them and is readily available if not recommended is this o.k. to use on the Fenix threads until I can get hold of something more suitable?

I also have an ITP A3 EOS upgrade (titanium) on order for my birthday will petroleum jelluy be ok on this until I can get something better?

I would not use a petroleum based product,use a good quality silicone grease ,if you have a shop near you that sells air rifles,they sell a special little pot of a lubricant for o ring seals on co2 weapons,works a treat on lights,it is red in colour and lubricates the seal and threads.There is a big thread on here all about lubricating,just put it in the search box and it will come up.The red lube oil is available in nearly all UK gun shops.

Although it is sometimes difficult to ascertain what o-rings might be made of, the point of choosing an appropriate o-ring & thread lubricant is that the choice shouldn't be a problem for any of the common o-ring materials. Please see the Comprehensive Grease and Lube Thread for more info.
