Female cap 2'' NPS thread

Female cap 2'' NPS thread (Reference: 100152) is an essential fitting component designed to provide a watertight and secure closure on valves and outlets of IBC tanks, industrial reservoirs and storage installations. Made from polypropylene reinforced with 30% glass fibers, this cap offers high rigidity and excellent service life, even in the most demanding environments.

Applications and use cases

This 2'' NPS female cap finds its place in numerous industrial and domestic applications. It is particularly suitable for temporary or permanent closure of valves on 1000L IBC tanks, water storage reservoirs, agricultural installations and rainwater collection systems. Construction professionals, farmers and individuals use it to secure their non-aggressive liquid storage installations.

In the chemical and food industries, this cap allows to shut off unused outlets while maintaining system integrity. Its compatibility with NPS (National Pipe Straight) threading makes it an element of choice for installations respecting American standards widely adopted in the IBC tank industry.

Technical specifications and innovation

The composition of polypropylene loaded with 30% glass fibers gives this cap exceptional mechanical properties. This formulation ensures high rigidity, good durability and increased resistance to mechanical and thermal stresses. Polypropylene also offers excellent chemical resistance to numerous liquids, weak acids, bases and organic solvents.

The 2'' NPS female thread (National Pipe Straight) respects standardized dimensions with a nominal diameter of 2 inches and specific thread pitch. Unlike NPT (tapered) threading, NPS threading is cylindrical, which facilitates assembly and disassembly while ensuring reliable sealing with corresponding valves. The precise dimensions guarantee perfect compatibility with standard valves of IBC tanks and industrial reservoirs.

Installation and use

Installing this female cap is simple and quick, requiring no specialized tools. Simply screw the cap onto the valve or outlet equipped with a 2'' NPS male thread following the usual rotation direction (clockwise to tighten). A firm manual tightening is generally sufficient to ensure sealing, avoiding over-tightening risks that could damage the thread.

For optimal use, it is recommended to check the thread condition before assembly and clean contact surfaces. When storing aggressive liquids, periodic verification of the cap's condition allows early detection of any degradation. Maintenance is limited to regular cleaning with warm water and mild detergent, followed by thorough rinsing.

Expert advice and product synergies

To maximize your installation efficiency, combine this cap with IBC valves and Multitanks fittings from our professional range. Camlock fittings, S60x6 to NPS adapters and ball valves constitute ideal complements to create a versatile and reliable fitting system.

A professional tip consists of marking the installation date on the cap to facilitate traceability and plan periodic inspections. Avoid prolonged exposure to direct UV rays which can alter polypropylene properties over the long term. In industrial environments, plan for spare caps to ensure service continuity during maintenance operations.

For seasonal applications like rainwater collection, this cap allows to temporarily shut off certain outlets during inactive periods, thus preventing debris infiltration and bacterial proliferation in unused pipes.
