1/2 A.B. PTC X 1/2 FNPT BRASS CON.

Description & Features

Designed for air brake system connections, this brass straight adapter from Aeroquip's Weatherhead line pairs a 1/2 in. push-to-connect end with a 1/2 in. female NPTF thread, providing a reliable swivel straight configuration in a single fitting. Brass construction suits the demands of air brake environments where corrosion resistance and pressure integrity are priorities.

The 1/2 A.B. PTC X 1/2 FNPT Brass Con. features Dura-Kote plating for added corrosion protection and is rated for operating pressures above SAE standards. Intended specifically for air brake systems, this fitting is not rated for use with fuel, water, or oil, and should not be used in environments where temperatures exceed +200°F or where battery acid exposure to tubing is possible. The Weatherhead line offers broad design flexibility across hundreds of styles, making it straightforward to source compatible fittings across a system.

Dura-Kote plating helps this brass connector stand up to corrosion, which should keep it reliable even with road vibration on air brake systems.
