The IDEAL Tridon 68 Series stainless steel worm gear hose clamps provide reliable, general-purpose hose sealing across automotive, industrial, plumbing and marine applications. Each clamp features a 9/16" wide stainless steel band (SAE 201) and stainless steel housing (SAE 301) to resist scaling and corrosion. The slotted 5/16" hex-head screw is SAE 410 low-carbon stainless steel, hardened to resist breaking and installable with a blade screwdriver, nut driver, or socket wrench. A worm gear mechanism allows precise adjustment of clamp diameter to apply uniform sealing pressure. The series is available in multiple SAE sizes to fit a range of hose IDs and ODs and is supplied in pack configurations (Pack of 10). Manufactured by Ideal Clamp Products.
