Valve Seat Seal DIN 7603 - A 22 x 27
Detroit Diesel

This steel valve seal ring serves a vital function in regulating air pressure within brake systems, specifically controlling the air flow to brake chambers. Its precise dimensions of 22 by 27 mm ensure a snug fit within the designated housing, preventing leaks that could compromise braking efficiency. Constructed from steel, it offers excellent wear resistance and longevity, even under repeated cycling and high-pressure conditions. Its role becomes especially critical during ABS operations, where accurate air pressure modulation is essential for preventing wheel lockup and ensuring vehicle stability. Although it is designed for compatibility with various Wabco systems, it must not be used on ABS valve packages to avoid malfunctions. Proper sealing provided by this ring directly impacts safety and performance, making it indispensable in maintaining the integrity of your braking system.
