Parker Push Lok - Ambient temp rating?

[MDrost1]

Folks,

I rebuilt my old neglect LW 4000 trough yesterday. Insulated with 1" foam board top, bottom and sides. Two layers on top. Constructed from pressure treated lumber with PVC cap and drip edge. Sponge foam weather stripping around the hinged doors. On a slab, flat roof.

Needless to say, it is much more "tight" than the old trough. I have some parker push lok(800 I believe), and some poly air lines.

I am on the lakeshore in MI. Our max temps get to about 90 during the summer. What is the max ambient temp rating of this hose? My assistant was concerned due to the tightness of the trough that hoses might get too hot and come loose from fittings(only LP soaps etc.) Is this some thing I need to even worry about?

Any advice is appreciated. Just want to make sure I am good to go. If not, want to fix it. Thanks!

I dont know what the temp rating is, bu I use them in the trough in my attic (SE PA). Summers high 90s outside are not uncommon - and I can tell you it is a heck of a lot hotter in the attic. Never had a heat related problem that I know of.

I am not sure what kind of "push lok" fittings you are talking about? I assume like the ones in the link?

I have not had any problems out of the (poly looking) parker "push to connect" or "liquifit" fittings in the south. That is basically all I use.... Parker or another brand.

I always try and replace all my fittings with parker push fittings. I do not care for the brass push fittings they seem to cause an issue if they get any product on them. I also do not care for the Parker "fast & tight" fittings just because they have 3 parts and you need a tool to open them.

I also have some "composite push-to-connect" and some ss ones but have not used them yet.

I see now.... I miss read your post.

I really doubt a car wash would ever have a problem with that push lok hose in any application with heat? It goes up to 100c and down to -40 working temp. As long as you use the correct fittings I have never had a problem. I mostly just use brass fittings but apparently they come in ss.

FWIW some of the RO systems use Parker Push Lok hose and run about 200 PSI - I've never seen one let go at a fitting, and it can get well above 120° in an equipment room here. I've seen the hose burst with high-pressure backing up from a bad check valve without pushing it off the barbs.
