ABST PEX Manifold,4 Loop Stainless Steel Floor Radiant Heat Manifold Kit with 1/2" Adapters Included for Hydronic Radiant Floor Heating

I was very happy with the quality and ease of installation of this manifold. I installed hydronic floor heating in a cellar where space was limited. This fit perfectly and controls the heating zones effectively. Highly recommended!

Works great, had a couple minor leaks, just had to snug fittings. Kept my 1200ft garage @ 70 degrees all winter with Rheem on-demand water heater.

Just got this 2 days ago. "LOOKS" like a quality product, but we will see how it is next winter. Will install this summer. Shipping was X-TREAMLY fast and no damage!

This item goes beyond my expectations and earns 5 stars. Exactly what I was looking for. Nicely packaged with everything you need. Arrived in perfect condition. I wanted something like a in-floor heating manifold for use with cooling a Tesla battery system. Tesla Mod3 batteries come with 2 loops each, and I have 2 batteries, so 4 loops was perfect. Adjust flow on the fly and see exactly what is happening.

The manifold matches the description and is complete. I haven't installed it yet, waiting for construction to be completed.

works great! Have this running a radiant system in a 30x30 shop and does an amazing job!

There are no instructions with the product or on Amazon. On Amazon the images identify visual flow meters as red and thermostatic handwheels as the white knobs. I couldn't get any flow through the manifold and then looked at the bottom of the Amazon product page and found that the flow indicators are stop valves and have to be un-threaded between .5MM and 4.8MM to open flow on the supply. The thermostatic handwheels also appear to control flow but there is no description on how these work and why are they necessary if you have to adjust the flow meters for flow? I would rate the product higher if I didn't have to spend hours to figure it out from no documentation.

Well built and leak proof. Would buy again.

I was slightly worried about the quality of the manifold and how compared to the brand name models. While I haven't used brand name manifolds, I was very impressed by the weight and quality of this manifold. The adjustment knobs work great and allow for fine adjustments. They even allow for full blocking of some loops. My system only has 9 loops and I was planning to install a short stub of PEX with a plug as insurance if the valves failed or had a slight leak, but I have yet to go back and do it and there are no leaks.

Très bonne qualité pour mon plancher chauffant de mon garage

This is a great manifold at a very reasonable price, compared to what you’d pay for a brand name one. My first one arrived with one of the red collars cracked so I exchanged it for a new one through Amazon. The plastic on the red collars does seem a bit brittle so I can see how that would happen, but they’re mostly decorative anyway. It was a bit tricky to seal the 1” NPT threads on the input and return (as others have said) but even the more expensive brand name ones suffer from this issue. I just went 25 to 30 wraps of teflon tape around it and it’s held just fine. Otherwise the manifold works just as well as a brand name one and has all the same features (for a fraction of the price). A great buy!

Check it out mine was missing a small hose retainer clip

Très bon produit, je suis vraiment satisfait! J’ai installé plusieurs systèmes de chauffage au Glycol et ce collecteur est de bonne qualité à un prix raisonnable.
