Valve question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**kev2809** · 12-05-2009, 06:15 PM

i have a question about hooking up the valves together. does it matter which side of the valve ("in" and "out") is facing when hooking them together? im running my 8 valves in sets of 2's for each corner. i just got my loctite in today and would like to fit everything together. thanks

**kev2809** · 12-06-2009, 11:56 AM

nobody knows this?

DHPmike · 12-06-2009, 01:02 PM

the direction definitely matters. If you have them backwards they will leak down.

almost all valves have and in and out.

texastrendz · 12-06-2009, 01:22 PM

mine had a little arrow on the brass where the pipe thread is at.

**kev2809** · 12-06-2009, 01:55 PM

ok thats what i thought. mine do have "in" and "out" on them. so the air from the tank goes to the "in" side, and the "out" side goes to the t fitting, to the "in" side of the other valve, and the "out" side (of the second valve) is just open, right?

DHPmike · 12-07-2009, 07:34 PM

yup, correct. be sure not to use teflon tape. it gets into valves and makes them leak. use thread seal or pipe dope sparingly. if you do get leaks just make sure the valves are where they can be taken apart easily while installed to be cleaned. They will pick up trash from time to time even if you have filters and screens.

**kev2809** · 12-07-2009, 11:45 PM

thanks. i started putting them together last night and already ran out of that .02 oz loctite that suicide doors sells. i cant believe that little bastard was 3 bucks. i only got 2 sets finished. i used a little more than "1 dot" to make sure. seems like you really cant put too much of that stuff on.

72hotrodder · 12-08-2009, 01:19 AM

just dont want to use enuff to were it can get into the air supply and damage the valve diaphram. when i was younger i had the more is better mentality to teflon tape and ruined a few valves. and that was back when they were about 60 a piece and befor i was smart enuff to ask

**kev2809** · 12-08-2009, 07:13 AM

ya, I was kind of hesitant to use the tape after reading a few threads on here. with the loctite, I put a drop or 2 on the first 3 threads. I just need to find a place local that has it

72hotrodder · 12-08-2009, 10:17 AM

lowes. in there plumbing department. its not made by loctite but just as good and cheaper

**kev2809** · 12-08-2009, 12:16 PM

I checked yesterday for some but I was only looking for that brand...not sure if I trust anything else

**kev2809** · 12-10-2009, 07:49 PM

would permatex high temp thread sealant work? only thing I can find! its liquid, says it prevents tapered metal fittings from leaking....so it sounds right. any help?

texastrendz · 12-10-2009, 07:54 PM

teflon tape, plumbers have been using it for years. i know i am going to get bashed for telling you this, i teflon taped every fitting in my truck and takes two months to go down. first dont tape over the fitting end, second rap it three times in the direction of the treads. it will be fine. if done right it will not leak and it will not get in the valves.

**kev2809** · 12-10-2009, 10:18 PM

i do have some if i need to use it. it has to work to some extent lol, thats what it was made for anyways. has anyone had any experience with what i listed above, or at least know it will work?

Hell ya I hate that pipe dope. I use teflon tape on all my installs. But do what texastrendz said and you'll be fine.

**kev2809** · 12-11-2009, 05:18 PM

thanks for the input guys. I may have to use it if nobody can chime in on this permatex stuff.

anyone? I would like to put the rest of my fittings together tonight!

**lolife99** · 12-11-2009, 07:23 PM

Go to Fastenal,... and get a bottle of Loctite 545. Good stuff.

**kev2809** · 12-11-2009, 08:26 PM

i never knew we have a fastenal here..lol. ima stop by tomorrow to check it out...

so this wont work?

said it was formerly called loctite 592..

this is what i already have so if it will work, i would not have to buy the loctite

67Fleet · 12-11-2009, 10:18 PM

Loctite 545 is the best stuff to use bar none. I got a 1.69oz bottle for like $10 shipped on ebay.

**kev2809** · 12-11-2009, 10:52 PM

lol yes i know. i only want to know if anyone has used this. i still havent opened it, which is amazing because i usually tear stuff up and waste it without asking anyone lol. but if i get any bad inputs i wont use it. soo...

I say,... YOU try it and tell us how it works.
I know Loctite 545 works.
Give us some feedback on your results.

**kev2809** · 12-11-2009, 11:30 PM

lol...maybe i should. just makes me hesitant to use it since nobody has any experience with it..

**lolife99** · 12-11-2009, 11:51 PM

And,... the bottle of Loctite 545 I bought was $29.00.
But that beats tearing eveything back apart, cleaning threads, reassembling, and leak checking again.

This is what Suicide Doors and other companies recommend.
Its a hydraulic thread sealer for high pressure joints.

Let us know how your product works. It may be a cheaper alternative.

*Shane* · 12-12-2009, 12:22 AM

Forget the Teflon tape and take lolife's advice ... Loctite 545 is head and shoulders above anything else out there.

texastrendz · 12-12-2009, 12:29 AM

i just don't get it. i work on commercial equipment everyday with hydraulic fittings. not one time have i seen a type of pipe dope, thread sealant or any type of liquid sealant. they all run teflon tape. it is what every house in the u.s.a has in it if has a gas line. why are yall so stuck on thread sealant. not mocking or talking sheeet, i just wanna know. thanks .
