KFL fill screw o-ring replacement

[slimfb]

hi all, hope this is in the right place.

the fill screw on my kfl clone came with a silicone o ring, quess it is a bit fragile or i have over tightened it, but it's bust.

after some snooping around i found a forum post somewhere else so i thought i would share.

i've just ordered these 0.99p for ten

i'm NOT going to try ptfe tape, slim chance but if that gets burnt on your coil it is extremely toxic

cheers

I use PTFE tape on my original KFL

i would say the slim chance is no chance .. its miles away from the coil and it DOES work.

nice one on the find tho .. defo worth an order for plus owners

the ptfe may shread on your screw threads & enter the liquid, i've just cut n paste the following :


You might want to read this before you risk getting PTFE particles on your coil!

Excerpts from The Toxicology of Perfluoroisobutene by Jiri Patocka and Jiri Bajgar.

Perfluoroisobutene ... is a fluoro-olefin produced by thermal decomposition of polytetrafluoroethylene (PTFE), e.g., Teflon [1].

Overheating of PTFE generates fumes of highly toxic PFIB and poses a serious health hazard to the human respiratory tract. PFIB is approximately ten times as toxic as phosgene [2]. Inhalation of this gas can cause pulmonary edema, which can lead to death. PFIB is included in Schedule 2 of the Chemical Weapons Convention (CWC), as a result of the prompting by one delegation to the Conference on Disarmament [3]. The aim of the inclusion of chemicals, such as PFIB was to cover those chemicals, which would pose a high risk to the CWC. Subsequently PFIB, specifically, was included in the final text of the CWC.

PTFE starts to decompose at 260°C and breaks down at 350°C.

Ordered some as I seem to keep losing the little buggers. Thanks for the link.

the o-ring on a keychain screwdriver should be the right size. If you have one of them around it could save you having to order a 10-pack online.

arrived today, quick !
now, to get them on, very fiddly !
this is what i ended up doing :
get a biro pen with a removeable inside (bit with ink in)
fit o ring over point & slide along till on plastic case, remove inside bit, push fill screw thread end where the inside bit was, slide o ring back down onto thread, bingo. i spent an hour trying to find a way & pinged off or broke 4 o rings, but hey 15 left :-)

I'll give that a try.
