Female Malleable Cast Iron Cap with Black Heart

Female Malleable Cast Iron Cap with Black Heart

The Black Core Malleable Iron Female Cap is an essential termination accessory, designed to reliably and securely seal the threaded male ends of your installations. This component is the ideal solution for temporarily closing a duct awaiting extension or for permanently isolating an unused outlet. It guarantees an impeccable seal within any plumbing or heating network. Made of malleable cast iron, this cap offers mechanical strength that ensures long-term reliability, even under pressure stresses. It's a simple but crucial safety feature for the integrity of your fluid system.

Crucial Role in Network Security

This female plug finds its place in a wide range of fluid dispensing applications. It is ideally suited for water, gas, steam networks, as well as for non-corrosive liquids and gases. Its use is fundamental in HVAC (Heating, Ventilation and Air Conditioning) systems, where it can be used to block an orifice for maintenance or the end of a line. As a closing part, it is indispensable for the safety of the installations. In addition, the trend of industrial furniture offers an aesthetic application to this stopper. Its black finish and robust appearance are prized for the finishing of metal structures (legs, uprights, cross-braces), bringing a much appreciated loft and vintage touch.

Commitment to Quality and Compliance with Rigorous Standards

The design of this cap complies with the highest quality requirements in the industry. The parts are manufactured and tested in strict compliance with international standards, including EN 10242 and ISO 49, which is a guarantee of performance and compatibility. The material used is malleable cast iron EN-GJMB-350-10, as specified by EN 1562. This material is chosen for its excellent robustness and durability in the face of thermal and mechanical stresses, ensuring unfailing reliability.

Foolproof Sealing and Anti-Corrosion Protection

The effectiveness of this cap is based on the quality of its thread and its surface protection.

• The cap has a cylindrical female thread (Rp) that meets ISO 7-1 (BSPT) standard. This thread is designed to accommodate a tapered male thread (R), ensuring a high-quality mechanical seal by compression during tightening. This type of thread ensures a secure and durable joint.

• To maximize its durability and rust resistance, each fitting has a black finish applied with a minimum thickness of at least 70μm (micrometers). This protective layer against corrosion is essential to maintain the integrity of the cap over time.

• Quality is a priority: each fitting is 100% tested to ensure that it is watertight when it leaves the factory. This unit verification ensures a perfect seal from the first installation.

Assembly Tips and Optimal Use

To get the best possible seal and a long life from this female plug, follow these recommendations:

• Preparation of the Junction: Make sure the male thread of the hose or plug fitting is clean and intact.

• Sealant: It is strongly recommended to use a suitable sealant (quality PTFE tape or fluid-specific gasket paste) on the tapered male thread to optimize the seal of the cap.

• Controlled tightening: Screw the cap on firmly, without excess. The tightening must be sufficient to create the necessary compression for sealing without damaging the threads.

• Verification: For pressurized networks (gas, steam), always carry out a check after the final tightening.

• Decorative Use: For industrial furniture, this stopper is an excellent finishing piece. Its black and matte appearance contributes to the final aesthetic of the furniture.
