These fittings worked out great for my project and they where nice quality fittings. The shipping time was very fast.

This was bought to add to a fawcett I also purchased - at at least 1/3rd of the cost through my normal Marine sites.
I am restoreing a 26' sailboat and will be looking for more items to purchase through them considering how much they have save me so far.

Works great on my Valterra Water tank!

As with everything I've purchased from etrailer, great description, quality and price.



by:

I've only used it once, to plug in my cargo trailer-->camper conversion into my house to test out the A/C. The adapter feels heavy duty and worked well. There's not much more I can say about it.

  • Can I Use the Flair-It PEXLock Male Adapter Fitting on the Reinforced Flexible Vinyl Tubing?

  • RV Fresh Water Connections for 1/2 Inch Tubing
    The Valterra Male Adapter - 1/2" MPT x 1/2" Barb - Polypropelene # RF841 and Valterra 90-Degree Male Adapter - 1/2" MPT x 1/2" Barb - Polypropelene # RF846 are just a couple of many fittings that will work with 1/2 inch tubing for your freshwater tank. We don't have a specific kit for that tube size, but adapters will give you what you need. I've linked the page to our freshwater fittings to assist.

  • Valterra RV Plumbing Fitting - Male Adapter - 1/2 MPT x 1/2 Barb
    The Valterra RV Plumbing Fittings are designed to thread into an unused hole on the water tank. The holes are usually either 1/4", 1/2", or 3/8".

These will then allow you to attach a hose via the barbed fittings with a hose clamp. The threaded side will require sealant like the Thread Tape part # A05-0265. They are offered in a few different...
