Conical Union M/F Galvanized Malleable Iron

The straight union Male/Female (MF) with conical seat is the key part wherever a demountable in‑line joint is needed. It connects a male pipe end to a female end in a straight line while allowing the connection to be separated later.

What is a straight union for?

Indispensable for installing and maintaining equipment on rigid pipework. By simply loosening the central nut, the union splits into two, freeing the connection without turning or cutting pipes. Main applications:

• Equipment installation: Ideal for water meters, pumps, filters, valves, or any device that may require periodic service.
• Join fixed pipes: Completes the connection between two fixed pipe sections (one male, one female) that can’t be rotated relative to each other.
• Create a break point: Inserting this fitting in a long straight run provides a strategic access point for future work.

Sealing of the union is achieved by a high‑precision metal‑to‑metal conical seat, eliminating the need for a flat gasket prone to wear.

Technical Features (EN 10242 Compliance)

Manufactured to EN 10242 for first‑class quality and reliability.

• High‑Quality Material: Malleable cast iron (EN‑GJMW‑400‑5).
• Anti‑Corrosion Protection: Hot‑dip galvanized (approx. 70 µm).
• Conical Seat Sealing: Union with metal‑to‑metal cone seat for durable sealing.
• Connection Threads: Combines a male taper thread (R) and a female parallel thread (Rp) to ISO 7‑1.

Installation Tip

Seal the Male (R) and Female (Rp) threads with a suitable product (hemp, PTFE tape, etc.). Do not apply sealant to the union’s conical seats. Tighten the central nut firmly to ensure metal‑to‑metal contact.
