REQUIRED for Installation
Pros: Quick installation once you have all of the necessary parts. No leaks so far.
Cons: I wish I'd have known that at least 2 are required to install the Manabloc when I ordered the unit. I had to place a separate order for these, which delayed installation.

overpriced
overpriced because it is a proprietary thread to match the viega threads on the manabloc. ensure you watch the pex videos on their website since there are many options to choose from. I recommend this product only because there are no options if you use the manabloc and the 1" pex tubing.

All Viega products are great. I would use nothing else for domestic water distribution.

Should be included with manifold but < shrug>
Only 4 stars because I think it should be included with manifold.
Nice fit. Solid construction. Expensive though and necessary. Make sure lines are coming in square so o-ring is seated properly

Great product
This is a hefty adaptor. It's easy to install and hasn't leaked. I wish Manabloc included it with their manifolds, but I get why they don't...depending on the number of lines you need to run, you may need the supply adaptor for the bottom outlet, or you may just cap it.

Product came ontime and the order was correct
Supply House saved me on my project. Did not realize I would need to change out my PEX Manifold inlet connectors. Ordered the items, they were here within one day. Awesome service at a fair price.

Q: I have a 1" PEX Crimp x MANABLOC Supply fitting. The "screw" ring does not fit over the tubing I bought at a local store. Is there no standard between manufactures of PEX tubing? How do I get this ring to fit since the tubing is alredy run?
Asked by Sean 15 years ago
Add your answer
Verified Reply- PexSupply StaffStandard PEX should always have the same dimensions. With this fitting, the tubing should fit over the barbed side of the fitting on the PEX side. You will need to complete the connection with a 1" crimp ring and a functional crimp tool.

1) Slide the "screw" ring into place on the supply fitting. 2) Slide the crimp sleeve over the PEX tubing. 3) Slide the PEX tubing over the barbed supply fitting. 4) Line up the crimp sleeve and crimp the sleeve in place. Sounds like you skipped Step 1 (??).

Q: What adapter do I need to attach the two, 3/4 inch braided water heater lines to the 1 inch ports?

Q: I have the Manabloc MXBD24-3XL and need the adapters for the main supply and water heater ports. All 3 will use 3/4" PEX, but it looks like the manifold has 1" pipe thread. Is the 3/4" adapter the correct one?
Asked by 16 years ago

Verified Reply- PexSupply StaffYes, the 3/4" adapter is correct.

- Aeppli
Yes, the adapters are standard-sized for connection to the manifold. The supply end varies based on the size of the supply line you're running to it. If you're using 3/4" PEX, you'll want the 3/4" adapters.
