Shoulderless Male Plug Galvanized Malleable Iron

The hot-dip galvanized malleable cast‑iron male plug is the go‑to fitting for reliably and permanently closing a pipe end or an unused female outlet.

What is this male plug used for?

Its main function is to blank off an unused female threaded opening. It hermetically closes a capped branch on a network, isolates an outlet on a manifold, or protects a thread from debris during works.

Its tapered thread design ensures perfect sealing once installed with the right sealing product.

Technical Features (EN 10242 Compliance)

Manufactured to European standard EN 10242—a mark of reliability and quality for pros and demanding DIYers—this standard guarantees precise characteristics:

• High‑Quality Material: Malleable cast iron (grade EN‑GJMW‑400‑5 to EN 1562), known for high mechanical strength under pressure and impact.
• Superior Anti‑Corrosion Protection: Hot‑dip galvanized finish with a zinc layer around 70 µm. This advanced protection ensures excellent service life, even in damp environments.
• Taper Sealing Thread (BSPT): Per ISO 7‑1, the male thread is taper (R). This profile seals effectively on the threads when tightened. Use of sealant (such as hemp, PTFE tape or a resin) is essential for a perfect connection.

Installation Tip

This plug generally has a square head for effective tightening with an open‑end or adjustable wrench. Apply sealant along the full effective thread length in the tightening direction before insertion.
