Wholesale 2 to 13 Loops Heating Radiant Manifold brass Collectors plumbing Manifold With Flow Meter and union For Floor Heating

The manifolds are generally made of CW617N or CU57-3 brass. We also use CW602N brass, CW625N brass, CW725N brass, etc., as the raw materials for manifolds body and internal parts such as balls and spindles. Various surface treatments can be offered according to customers' requirements, such as nickel plating and polished chrome plating. All of our manifolds are forged and formed with a thickness of 3 mm-4 mm, which can prevent the leakage of water.
The manifolds and spindles are both processed by CNC machines, so the spindles can precisely match with the manifolds. At the same time, high temperature and wear resistant EPDM material is adopted to make the sealing rings to guarantee a long service life. Our regular sizes are 3/4" and 1", and the three different threads are 16 mm x 1/2", 22 mm x 18 mm and 24" x 19 mm.
In order to ensure the leak proof of the product, every single manifold will be tested by using water pressure machine before sending to customers. Endurance tests for manifold are also done frequently to make sure the products can be “open-close” for
minimum 10,000 times.
