Product Overview – Hi-Torque Clamp Stainless Steel 4.25 in to 5.13 in
The OTX-4SCH512 is a hi-torque hose clamp sized for 4-1/4 in to 5-1/8 in (108–130 mm), used by fleets and workshops on heavy-duty hoses and ducts.
Hi-torque clamps use a heavier housing and wide band to reach higher clamping loads than standard worm gear clamps, making them a good fit for large hoses, ducts and air intake connections.
Construction: a 301 stainless steel band 5/8 in wide, a 410 stainless steel screw with a 5/16 in hex, with a torque rating of 150 in-lbs.
