Pex spare parts

[GordSanClemente]

Hi Folks,
Another thread mentioned having spare PEX parts. I didn't want to hi-jack that thread with my question.
I have never used any PEX.
What are the spare pieces you would take. (Pretend like you are talking to a 7 year old)

Are any special tools required for this stuff?

BTW - I already carry spare fuses, crimp connectors, various tapes, JB weld,
Any other stuff folks carry?
thanks,
Gordon

This is all I would take:

The crimper and crimp rings. Anything else you can get at any hardware store like Ts, elbows, short pieces of PEX, etc.

All of the hardware and big box stores carry Shark Bite push connections so all you need are cutters less than $20. at same stores.

This is the same type clamps used on my last 2 5th wheels that all needed tightened.
Would recommend this set & as mentioned the big box hardware stores sell any fitting you may need.

There are problems with the crimped connections nothing bad about push connections and no tools needed and they are reusable.

You can buy a lot of PEX parts for the price of a few "Sharkbite" fittings.

I carry a foot of pex and two female-female end butt connectors and a pair of vice grips to shut off any line by pinching it.
That's all I carry.

I can actually in real life only reach about 5 percent of the pex in the rv, but the kit was cheap, and it doesn't spoil or expire.

Sure can. But buy the shark bites anyway. You’ll have a nice assortment for $25 instead of $2.50 but they are foolproof and super easy to use.

yeah, that's not the kind of trip critical system that I carry parts for...unless I did a lot of way off grid boon docking. Otherwise you can get what you'll need almost anywhere... in the VERY unlikely event that you do need it

Surprising- Prior 36 ft Dp, GeorgieBoy used plastic fittings on the PEX, I was able to replace all the fittings in the whole RV, with brass and rebuilt the water manifold. Looking at present Siesta I think most is accessible.

For the OP all the PEX in your RV is probably 3/8 inch. Tools, fittings and clamps at big box.
On the road, a PEX 3/8 sharkbite end cap to stub a leak should get you to actual repair.. Then figure out what parts you need.

Nope, 1/2 inch.

Of course.
I've never seen anything else than 1/2 but I've seen a couple of dozen.

3/8th's guy:
Do you have a link?

[Hooligan2]

Ouch! You are correct, outside diameter is 1/2 inch, just checked- labels on my parts are all 1/2 inch..... I tried using inside diameter..
FWIW Watts also makes plastic slip on connectors similar to Sharkbite.

I’ve had to do a few in-situ repairs over the years - mostly to friends’ rigs and not my own. Here’s what I carry:

- two 4’ pieces of 1/2” PEX, one each of blue and red
- a handful of straight connectors
- a handful of plugs (useful for cutting and isolating a line until you can get into a better situation)
- a handful of elbows
- a couple of quarter turn valves
- a plastic tubing cutter (also works well on dog rawhides if big enough)
- 20 or so crimp rings
- crimper
- crimp/pipe removal tool.

So far, I haven’t run into anything I can’t fix on the road (broken/leaky valve, split elbow, cut pipe).

The Sharkbite tool-less connectors are also quite handy. They’re much more expensive, however. You’d likely only need a cutter, some pipe and a few different types of connectors if you went that route.

I added an external shower to my Class C. Push Pex fittings [not clamps] were used between the existing plumbing and the new shower head. I couldn't have gotten the crimping tool into the area under the refrigerator if I had wanted to use crimp fittings. Fittings and an 8ft length of pipe were purchased at Lowes or Home Depot.

BTW: Pex pipe and fittings are more resistant to bursting when frozen than brass/copper pipe.

Has anyone had any luck getting the flexible clear braided 1/2 inch tubing that works with pex 1/2 inch fittings? I have a 2015 36.5 Palazzo and want to add a pressure accumulator to the fresh water system, as well as have flex hose into and out of the water pump to reduce vibration and noise (Thor used rigid pex for that). In my rig, whenever Thor made a transition from rigid pex to flexible, they used a 1/2 inch pex coupler to a similar-sized clear, braided tube and used a pex clamp to secure it. The flex hose has the “Accuflex” name on it, but it’s not produced or called that anymore. I tried a similar looking (and specked) “1/2 inch” hose from Kuryama, but neither the pex barbs nor the clamps fit properly (barbs are loose and the clamps are too small). Thanks!

I could "just barely" get my hand with the sharkbite in there.
Don't even want to talk about cutting the bad piece off .
