This product is made of PEX material, not metal. And main inlet and outlet adapters are not included. Please add #50141 manabloc adapters and/or V5036.10 manabloc end cap to complete installation. **Q: Can one use a regular pex crimps?** A: Make sure you get the pex crimp version. This one has the pex tubing attach with Compression fittings that need a special wrench from Viega to be able to easily do them all. **Q: does this include the supply adaptors for the 14 ports?** A: Those are the outlets and it has more than enough. Just make sure you order the manibloc that has what you want. Some are 1/2 in pex crimps, some are others. Make sure you read the ad to see which one. You will need 2 supply adaptors and a cap or three supply adaptors and no cap depending on how you're using it. Those are separate **Q: can this manifold be installed in a crawl space?** A: I installed the one that I got in the crawl space under our cabin in an insulated box that we built for our hot water heater. During freezing temperatures when the water lines are not drained the manifold is kept warm by the residual heat given off by the water heater. if the manifold has water in it and the temps reach freezing, the manifold will probably break. Unlike pex plumbing, the manifold is not designed to freeze without breaking. ## Frequently Bought Together - Viega 50143 - 1/2-Inch PureFlow Zero Lead Poly Alloy PEX Crimp Manabloc With 14 Ports - 8 Cold 6 Hot - Pronese 3 Pack Pure-Flow & Lead-Free Polly Alloy Brass Pex Crimp Supply Adapter, 3/4 Inch With 1 Copper Ring Crimp For Supply Line - Viega ManaBloc V5036.10 Brass PEX Supply Cap, 1" --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/305603147-50143-1-2-inch-pureflow-zero-lead-poly-alloy-pex](https://www.desertcart.us/products/305603147-50143-1-2-inch-pureflow-zero-lead-poly-alloy-pex) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-22*
