412 704 002 0 WABCO Twin Cylinder, Air Compressor

This high-strength twin cylinder air compressor is engineered to provide reliable pneumatic pressure within heavy commercial vehicle brake systems. Designed for durability under intense operating conditions, it features a water-cooled valve plate and a precision-engineered Ø85.00 mm cylinder bore to ensure consistent performance.

The 4127040020 is the OE equivalent of the WABCO 4127040020 air compressor used in professional heavy-duty systems. This component is specifically designed for compatibility with WABCO hardware and high-performance braking architectures. It features a dual-cylinder configuration with a 62 mm stroke and a 704cm³ swept volume to meet stringent industrial standards.

Installation for workshop technicians should be performed according to standard braking system protocols. The unit includes an M26x1,5 air outlet port and an M16x1,5 water inlet/outlet configuration to facilitate efficient thermal management. Regular inspection of the water cooling ports and the ESS feature integration is recommended to maintain optimal system pressure and prevent overheating during long-haul operations.
