Product Overview – T-Bolt Spring Load Hose Clamp 2.63 in to 2.94 in
The OTX-4ST263B is a spring-loaded T-bolt clamp sized for 2-5/8 in to 2-15/16 in (67–75 mm), used by fleets and workshops on charge air cooler, turbo and intake hoses.
The spring-loaded bolt compensates for hose cold-flow and thermal cycling, a common cause of charge air leaks on turbocharged diesel engines.
Construction: a 301 stainless steel band 3/4 in wide, a zinc plated carbon steel screw with a 7/16 in hex, with a torque rating of 150 in-lbs.
It cross-references to OEM part number Mack 21922388 and 5 aftermarket numbers, so you can match the exact clamp you are replacing.
Tip: replace clamps whenever a joint is opened for service; a used clamp may not seal to the same load.
Contact OneTouch Exim with your OEM or competitor part number and we will confirm fitment and quote the OTX-4ST263B.
