Threaded straight connector Valsir 20x3/4" GZ 100612

Threaded straight connector Valsir 20x3/4" GZ 100612 is a straight coupling designed to join or extend piping runs where a 20 mm nominal pipe needs to connect to a 3/4" male threaded fitting. Manufactured by Valsir, this connector provides a simple mechanical interface between smooth or pipe-end fittings and threaded components in plumbing and heating systems. The product is intended for installations where a reliable, compact threaded connection is required and where compatibility with standard 20 mm pipes and 3/4" female threads is expected.

Advantages

The connector features a compact straight design that minimises space requirements while providing a direct threaded connection. Its straightforward construction allows fast installation and replacement in existing pipeline runs. As a dedicated threaded coupling for 20 mm to 3/4" interfaces, it reduces the need for adapters and ensures a consistent thread engagement. The part is suitable for use in water supply and heating circuits where a metal-to-thread or pipe-to-thread connection is needed.

Suitable for

• Joining 20 mm nominal pipes to 3/4" female threaded fittings
• Repair or replacement of short sections in water supply lines
• Connection of heating system components with 3/4" threaded ports
• Situations requiring a compact straight threaded coupling in plumbing installations

Key specifications

• Nominal pipe diameter: 20 mm
• Thread type and size: 3/4" male thread (GZ)
• Connection style: straight threaded connector
• Typical application: water supply and heating circuits
• Manufacturer: Valsir

How to use

Prepare the pipe ends and the mating threaded fitting by ensuring they are clean and free of debris. If using plastic or metal pipe, cut squarely and deburr edges. Apply appropriate sealing material to the male thread (for example, thread seal tape or approved sealant) following the sealing product's instructions. Hand-start the thread, then tighten with an appropriate wrench until a secure, leak-tight engagement is achieved without over-tightening. After installation, pressurise the system and check for leaks at the connection; if necessary, re-tighten slightly or reapply sealant and reinstall.

Usage recommendations

Use the connector only with compatible 20 mm pipes and fittings designed for potable water or heating systems. Select a thread sealant suitable for the system medium and temperature range. Avoid excessive torque during tightening to prevent thread damage; follow standard plumbing practice and local codes for pressure testing and installation.
