Female cap in galvanized malleable cast iron

Female cap in galvanized malleable cast iron

The galvanized malleable cast iron female plug is a high-performance closing element, designed to permanently and securely seal any threaded male end. Thanks to its hot-dip galvanizing coating, this cap offers exceptional corrosion resistance, making it indispensable for installations exposed to moisture, weather, or aggressive fluids. It is the ideal solution for temporarily or permanently completing a piping line, guaranteeing perfect sealing and increased longevity of the entire network.

Reliability in Demanding Environments

The galvanized finish gives this female plug essential versatility for many applications. It is widely used for the distribution of water (including drinking water), gases, steam and for the transport of non-corrosive liquids and gases. Its rust resistance makes it particularly relevant for HVAC (Heating, Ventilation and Air Conditioning) systems outdoors or in humid environments, where fitting protection is crucial. Apart from fluid networks, the raw and silvery appearance of galvanized malleable cast iron is highly sought after in decoration. This stopper is used to give a clean and authentic finish to industrial furniture structures (shelves, frames, light fixtures), fitting perfectly into a loft or vintage style.

Quality Certification and Standardized Materials

The design of this cap complies with the highest industry standards to ensure flawless quality and reliability. The parts are manufactured in strict compliance with the international standards EN 10242 and ISO 49. The base material is malleable cast iron EN-GJMB-350-10, as required by the EN 1562 standard, which is recognized for its mechanical strength and resilience. The galvanizing process adds a protective layer of zinc, significantly improving the durability of the fitting against external aggressions.

Foolproof Sealing and Galvanic Protection

Sealing efficiency is ensured by the combination of precise threading and superior surface protection.

• The cap has a cylindrical female thread (Rp), which complies with ISO 7-1 (BSPT). This thread is designed to fit the tapered male thread (R) of the pipe or plug fitting, ensuring optimal mechanical sealing by compression during tightening.

• Hot-dip galvanizing is applied with a minimum thickness of at least 70μm (micrometers). This protective coating is a highly effective anti-corrosion barrier, essential for the longevity of the cap under the most demanding conditions.

• Confidence in quality is total: each fitting is 100% tested to guarantee its tightness when leaving the factory. This unit verification is the best guarantee of a secure seal.

Recommendations for Optimal Assembly and Use

To ensure a secure seal and a long life for this galvanized cap, follow these assembly recommendations:

• Preparation of the Junction: It is advisable to ensure that the male thread of the pipe to be plugged is clean and in good condition before installation.

• Sealant: It is crucial to use a high-quality PTFE tape or a specific gasket paste on the tapered male thread to optimize the tightness of the female plug.

• Controlled tightening: Screw the cap firmly with suitable tools. The tightening should be sufficient to engage the seal, but controlled to avoid damage to the threads or galvanization.

• Verification: For pressurized systems (gas, steam), a post-installation leak check is a mandatory step.

• Decorative Use: For industrial furniture, the galvanized finish can be left raw, but regular cleaning will maintain its shine.
