## Long description

Angle radiator union Fitting SF63-1 with 1 O-ring (Śrubunek grzejnikowy kątowy) is a compact plumbing fitting designed to connect radiator valves to pipework at an angle. The fitting incorporates a single O-ring seal to provide a leak-resistant joint and is intended for use in water-based heating systems for both residential and commercial installations. Its angled configuration reduces the need for additional elbows and simplifies alignment between valve outlets and supply lines.
Advantages
The single O-ring design ensures a reliable, compressive seal without the need for thread tape or sealant when installed correctly. Its compact angled body allows for neat, space-saving connections close to the radiator, improving accessibility for maintenance. The fitting is compatible with standard radiator valve dimensions and is constructed to withstand typical heating system temperatures and pressures when used as intended.
Suitable for
Connecting radiator valves to heating system pipework at an angle
Residential central heating installations
Commercial heating assemblies where compact connections are required
Replacement or retrofit of existing radiator unions
Key specifications
Type: Angled radiator union with integral O-ring seal
Seal: Single elastomer O-ring for leak resistance
Application: Water-based heating systems (radiators)
Installation orientation: Angled connection to match valve and pipe alignment
Compatibility: Designed to mate with standard radiator valve fittings
How to use
Ensure the heating system is isolated and drained as required before disconnecting any fittings. Position the angled union so the O-ring faces the mating surface on the radiator valve or pipe connector, then hand-start the threads to avoid cross-threading. Tighten to the manufacturer's recommended torque or until a firm compressive fit is achieved, taking care not to over-tighten and deform the O-ring. After installation, restore system pressure and inspect the joint for leaks while the system is cold and again after reaching normal operating temperature.
Usage recommendations
Use a new O-ring if the fitting is reused or if any damage to the sealing surface is observed. Do not use aggressive sealants on the O-ring; ensure mating surfaces are clean and free of debris. Follow local plumbing codes and the radiator valve manufacturer's guidance for installation and pressure testing.
