Re: sealant/tape

Teflon tape is teflon tape, any auto parts store or hardware store carrys it. liquid thread sealer? depends on the application, Permatex has some.

Re: sealant/tape

teflon tape is not a sealant ... it is a lubricant.

it allows the threads to tightened more in order to make more uniform contact between the thread faces which in turn makes the seal.

Re: sealant/tape

Loc-tite makes a thread sealant. It's in a red bottle. Just don't use the thread locker.

It also allows the unknowing to overtighten there fittings causing splits cracks and or pulled threads..

been around pneumatic and hydraulic fittings a long long time and can honestly say I've never seen this happen. especially considering pipe threads (NPT) are DESIGNED to deform in order to make a uniform seal.

sounds more like a Sasquatch wanna-be not knowing what he is doing ...

but hey, don't take my word for it ... google it ... let me help.

Re: sealant/tape

they actually have diffrent grades of telfon tape. i like teflon tape because it can be used in a wet application. i know air lines are not hydraulic lines but loctite would never work in a wet application. i have used teflon tape with great success and will never use anything else. i have heard that the loctite actually dries hard, does vibration on the road cause issue with this?

Re: sealant/tape

loctite 545 works in wet (hydraulic) applications. very well, actually.

loctite hydraulic/pneumatic thread sealant (purple-545) is not the same chemical compound as loctite thread locker (red-271, green-290 or blue-424).

justa fyi.

correct you are sir, i left out the important part(dam). in the field is the condition i am talking about. it has a cure time where tape does not. sorry i forgot to state that. i have had nothing but bad luck with anaerobic sealants. maybe not enough patience.
