Comap transition nipple 1/2" x M22 with O-ring for distributor 9800 (MPN 9810621)

Comap transition nipple 1/2" x M22 with O-ring for distributor 9800 is a compact hydraulic adapter designed to connect a 1/2" pipe thread to an M22 female fitting used on distributors and manifolds. The part includes an O-ring to provide a reliable seal at the joint and is made to match the interface dimensions of Comap distributor 9800, facilitating direct replacement or integration during installation and maintenance of heating and plumbing systems.

Advantages

The transition nipple provides a precise mechanical fit between different thread standards while the supplied O-ring improves sealing performance and reduces the risk of leaks. Its compact design minimizes flow restriction and simplifies installation in confined manifold cabinets. Manufactured to match distributor interface geometry, it supports straightforward replacement without modification of the existing piping layout.

Suitable for

• Connecting 1/2" threaded pipes to M22 female fittings on heating distributors and manifolds
• Replacement of worn or damaged adapter fittings on compatible distributor models
• New installations where a secure hydraulic connection between different thread standards is required
• Maintenance tasks that require a sealed transition with minimal modification to existing piping

Key specifications

• Connection types: 1/2" male pipe thread to M22 female fitting
• Seal: integrated O-ring for axial sealing
• Application area: hydraulic connection for manifolds and distributors in heating and plumbing systems
• Form factor: compact adapter suitable for confined installation spaces

How to use

Before installation, verify compatibility with the distributor or manifold by checking thread types and clearances. Ensure mating surfaces are clean and the O-ring is correctly seated in its groove. Hand-start the threads to avoid cross-threading, then tighten to the required torque using a suitable wrench or spanner. Do not overtighten; follow torque guidance from the distributor manufacturer if available. After installation, pressurize the system and inspect the joint for leaks, re-torquing if necessary within recommended limits.

Usage recommendations

Use the transition nipple with compatible Comap distributor interfaces and in systems operating within the pressure and temperature ranges specified by the distributor. Replace the O-ring if it shows signs of wear or damage during maintenance. For best long-term performance, avoid exposure to abrasive contaminants and ensure routine inspection of manifold connections.
