Radiator Tailpiece with Nut IMI TA 15 Straight M22x1.5

Ensure a tight, stable, and highly dependable fluid path to your radiators with this straight tailpiece and nut configuration from industry-leading IMI Hydronic (formerly TA). 

This premium-grade radiator coupling is specifically engineered for professional fixed installations within water-borne hydronic heating networks. By offering an exact structural tolerance match, it dramatically simplifies the mounting process between the radiator valve and the pipework manifold, eliminating micro-leaks within the property.

Heavy-duty architecture in advanced metallurgy
The coupling body is manufactured from IMI's proprietary high-performance brass alloy, Ametal. This compound is celebrated for its exceptional resistance to dezincification and stress corrosion, granting the union an incredibly prolonged service lifespan even under constant thermal cycling and demanding operational parameters. To supply an added layer of surface shielding and a clean aesthetic that complements modern valve housings, the brass is completed with a durable nickel-plated finish. 

Precision threading for leak-free connections
This model features a streamlined straight profile orientation equipped with one male and one female mechanical thread interface. The connection profiles are standardized to R15 (3/8-inch nominal diameter matching the radiator side) and a fine M22 x 1.5 thread profile on the coupling side, ensuring seamless compatibility with a broad array of radiator valves and manifolds on the market. The connection piece arrives completely ready to install as a factory-paired tailpiece and nut pack.

Product Benefits:

• Ametal composition: Engineered from a specialized brass alloy that counteracts dezincification and mechanical stress.
• Nickel-plated shield: Provides long-lasting external protection while matching your valve body aesthetic.
• Standardized dimensions: Exact threading parameters (R15 x M22) secure a tight and trouble-free mechanical seal.
• High operational rating: Robust engineering comfortably manages the internal forces of closed climate loops.
• Ready-to-assemble kit: Arrives pre-packed with both the straight tailpiece block and the matching union nut.
• Long-term security: Reliably seals your radiator connection interfaces against weeping and drop-pressures.
