Product Description
The VIEGA 36003 is a plastic lock-in nut designed for use with the Viega ManaBloc plumbing manifold system. This fitting component secures port connections at the manifold body, maintaining a leak-resistant seal in residential and light commercial water distribution systems. At 1/2 inch CTS sizing and weighing just 0.04 pounds, it is a compact, lightweight replacement or service part. Licensed plumbers and pipefitters install this nut during ManaBloc manifold assembly, port servicing, or when repairing an existing installation. Its plastic construction resists corrosion in potable water applications where metal fittings may be unsuitable.
The 36003 lock-in nut is used specifically with the Viega ManaBloc manifold system in residential water distribution installations. It fits 1/2 inch CTS connections at individual manifold ports, making it a common service part when replacing damaged port nuts or completing a new manifold installation. This component is manufactured in the USA and suits both new construction and retrofit plumbing work where ManaBloc manifolds distribute hot and cold water lines to fixtures throughout a structure.
