The Midland Haldex SC20L is a Size T20 long-stroke service brake chamber for air brake systems. It delivers 2.50 inches (64mm) of available stroke, with a stud spacing (E dimension) of 4.75 inches (120.7mm) using 5/8-11 UNC studs, and a pushrod length (J dimension) of 10.00 inches with 5/8-18 UNF pushrod threads. The steel pressure housing is powder-coated with resistance-welded air ports. Air port threads are 3/8-18 NPTF, with the air port positioned at 90 degrees and service clampband at 0 degrees. Maximum rated air pressure is 150 psi. The diaphragm is rated for flexibility down to -40 degrees F. Call us to confirm proper fit for your application.
