Female Threaded Cap in PVC

Female Threaded Cap in PVC-U (Reference: 5302) - Multitanks presents a professional connection solution designed for the most demanding hydraulic installations. This high-performance female cap in PVC-U (Unplasticised Polyvinyl Chloride) meets the strictest industry standards with its PN16 certification and internationally recognised BSPP standard thread.

Applications and Fields of Use

This female threaded cap finds its place in numerous professional and domestic applications. Plumbers use it to temporarily or permanently seal pipelines during maintenance work or network modifications. In industry, it enables the secure closure of pipe ends carrying fluids under pressure up to 16 bar.

Landscape designers adopt it for their automated irrigation systems, while DIY enthusiasts appreciate it for their domestic cold and hot water installations. Its versatility also makes it an essential component for compressed air distribution networks and industrial cooling circuits.

Technical Characteristics and Materials

PVC-U (Unplasticised Polyvinyl Chloride) is the material of choice for this cap, offering exceptional resistance to mechanical and chemical stresses. Its nominal pressure PN16 guarantees safe use up to 16 bar at ambient temperature, with a safety margin adapted to common pressure fluctuations.

The BSPP (British Standard Pipe Parallel) thread ensures universal compatibility with European and international standards. This standard guarantees precise threading and optimal sealing through the use of appropriate sealing compounds. The available diameter range from 3/8'' to 4'' covers all common requirements, from small domestic plumbing to medium-scale industrial installations.

The dimensional stability of PVC-U guarantees the maintenance of manufacturing tolerances over time, preventing untimely loosening or leaks due to deformation.

Installation and Implementation

The installation of this female cap is carried out by simple manual threading, without specialised tools for smaller diameters. For larger sizes, the use of a strap wrench or pin spanner allows optimal tightening without damaging the material.

Surface preparation: Thoroughly clean the male thread of the pipeline, removing any traces of dirt, scale or old sealing material. Check the condition of the thread and identify any defects likely to compromise the seal.

Sealing: Apply a suitable sealing product (PTFE tape, thread sealant paste or hemp fibre with paste) to the male thread before threading. This crucial step guarantees a perfect and lasting seal.

Maintenance: PVC-U requires no particular maintenance. A periodic visual inspection is sufficient to check for the absence of cracks or deformation. In the event of disassembly, always renew the sealing material.

Expert Tips and Optimisation

To optimise the service life of your installation, pair this cap with fittings of the same quality. Multitanks offers a complete range of fully compatible PVC-U PN16 fittings, enabling the creation of homogeneous and reliable systems.

Sizing tip: Always favour a diameter slightly larger than the minimum requirements to facilitate future maintenance operations. This approach also allows for possible network modifications without complete replacement.

Storage and handling: Store caps in their original packaging, away from UV rays and extreme temperatures. PVC-U retains its mechanical properties over very long periods under appropriate storage conditions.

For outdoor installations, protect connections against frost by means of insulation or seasonal draining. Although resistant, PVC-U can be subjected to significant stress during the expansion of frozen water.
