Air fitting sealant.

[130man]

Hi all, I have discovered a leak in the airline fittings on my Left rear air spring where two metal threaded couplings join. I used the Pink Teflon Tape when I did the install but that has clearly failed. What would people suggest I use to make the threaded joint permanently air tight? All I have available right now is Silastic and some Loctite thread lockers of different strengths . Would these do or do I need something else Thanks, 130man.

Loctite 567 pipe sealant works well.

Hi I generally use loctite hydraulic / pneumatic sealer...but at a pinch I would use the low strength loctite tread sealer ...Gary

Thanks guys, I appreciate the fast response. I will be in town tomorrow and will chase up the pipe sealant if I can. Cheers 130man.

Are the threads taper or parallel? Taper threads seal on the threads and use tape, pipe sealant, hemp, paint, etc. Parallel threads seal at the interface using a gasket, fibre or copper washer, o-ring etc.

Stag jointing paste, regards Frank.

Thanks Brian and Frank, I will check out the threads in the morning. Stag paste rings a bell. Has it been around for quite a while? Cheers,130man.

Stag? It's as old and well trusted as greatgrandpa.
You might also check out "Goldend Paste" or the same name tape, from Chesterton.
Used in the Nuclear Industry, so it seals, "but good".

Thanks Shorty, I will chase up the suggestions later today when I get into town. I have been out fighting a grass fire all evening. Cheers, 130man.

Loctite has white tube thread sealant.565 ish or in a red liquid form.

the white Teflon stuff stays soft and messy-used where you use Teflon tape.
much better than stag.

the high pressure pipe sealant and lock is a yellow colour and sets like araldite [2 pack glues].

very good and clean.

I'd be interested in why you have two metal threads joining,,

I can only ASSUME there are plastic lines from a supply to the bag?

[130man]

Hi everybody, thanks for all the input. As it turns out I had to go to Bunnings for other stuff so I enquired there and ended up buying " Boston Liquid Sealant" for all gas and water pipe metal threads with a temperature range of -20C to 135C. It claims approval by the Australian Gas Association. Unless someone knows something bad about this product, I will use it in the morning. Setting time 10 to 20 minutes and requires hand tools to dismantle.

[Blknight.aus]

the white version of it is basically a re-built loctite product.

Apparently pressing "enter' by mistake automatically submits the posting. Sorry about that. In my set up the airline from the airspring to the valve is a short length of 1/2" airline left over from my nail gun days and has a female coupling with an air line fitting at one end and an adaptor to step down to a Schrader valve at the other. This is where the leak was. The reducer fits through an aluminium angle bracket and into the coupling and locks the whole thing to the bracket. Hence the two metal sections needing to be screwed together. I hope that makes sense. Cheers, 130man.
