Connector Red Marka ABG H20 — Holender 20 adapter (H20)

Red Marka ABG H20 — Holender 20 adapter (H20) is a compact Holender-type connector intended for joining or disconnecting plumbing fittings with a 20 mm nominal size. The adapter creates a threaded quick-connection interface that allows a removable sealed joint for water supply lines, radiator connections and general household plumbing. Its compact form factor is designed for installation in confined spaces and for routine maintenance where a reliable detachable connection is required.

Advantages

The connector offers a simple, tool-friendly threaded coupling that enables fast assembly and disassembly without permanent fittings. Its design ensures a sealed connection suitable for potable water and heating circuits when used with appropriate seals. The compact dimensions reduce the need for additional adapters and shorten installation time, while the standardized 20 mm nominal size makes it compatible with common plumbing pipes and fittings.

Suitable for

• Connecting or disconnecting 20 mm water supply pipes
• Radiator inlet and outlet connections that require a removable joint
• Temporary or permanent plumbing installations where a threaded quick-connection is needed
• Maintenance tasks that require frequent disassembly of fittings

Key specifications

• Connector type: Holender-style threaded adapter
• Nominal size: 20 mm
• Function: Removable sealed joint for plumbing connections
• Typical applications: Water supply lines, radiator connections, household plumbing
• Form factor: Compact design for use in confined spaces

How to use

Install the Holender 20 adapter by ensuring mating pipe ends and fittings are clean and free of debris. Apply the appropriate sealing element (such as a rubber O-ring or compression ring) compatible with potable water or heating systems, then thread the adapter onto the mating fitting by hand and tighten to a firm, leak-free fit using suitable tools if required. Check the connection for leaks under normal working pressure and re-tighten or replace seals if necessary. For radiator connections, follow the radiator manufacturer's instructions for orientation and torque limits.

Usage recommendations

Use seals and installation practices that comply with local plumbing codes. Avoid overtightening metal threads to prevent damage to the connector or mating fittings. Inspect connections after the first period of operation and during routine maintenance to ensure sealing integrity.
