Barstock Fittings & Max Operating Pressures

[Rfreeman]

Hey guys I am in the process of a complete remodel at a 6 bay SS wash I recently purchased. I am redoing the low pressure (LP) and high pressure (HP) lines and in assembling the manifolds for the LP and HP functions I noticed on KleenRite's site some of the barstock fittings have a max operating pressure of 1200 PSI more specifically:

Union Tee:

Brass Union Tee, 3/8 in. | 28-026 | Barstock Fittings

Connect three pipes or hoses featuring 3/8" male NPTF ends with ease with the 28-026 union tee, featuring 3/8" female NPTF openings.

Hex Nipple:

Brass Hex Pipe Nipple Fitting, 3/8 in. | Car Wash Fittings | 28-213L

Connect two pipes or hoses featuring 3/8" female NPTF ends with ease with the 28-213L brass hex pipe nipple fitting. Kleen-Rite brings you the best in brass fittings for a lightweight, streamlined hydraulic, gas, or fuel system at smart prices.

QUESTION: I run my pressure at 1200 PSI which is the max rating on these 2 fittings so the last thing I want to do is start dealing with leaks after opening, have any of you guys used these fittings at 1200 PSI? Do you think I would be okay considering I am going to be running at the max pressure rating?

Thanks guys for your feedback that's what I was thinking but double checking this is my 3rd wash but 1st ever complete remodel. I am talking about gutted the equipment room and starting all over with a used Coleman pump stand, all new nylon LP lines, HP lines, new meter boxes etc.

My supplier's catalog lists the flare to MPT fittings at 2000 PSI working pressure, and those fittings are machined from barstock.

FWIW, the ones Kleen-Rite sells are not very good, I've had tees start to leak after a few years on LP systems without even caustic chemicals running through them. Windtrax carries Parker brass fittings, more expensive than Kleen-Rite's but well worth it. Windtrax lists them at one price on their site but they're much less on the invoice.

We've been using stainless steel fitting and never have a problem with them. We use Leak Lock to put them together.
