The MIDLAND INDUSTRIES 500088 is a quick-release worm-drive band clamp from the 500 Series, designed for fast, secure clamping in plumbing, HVAC, and industrial piping applications. Constructed from 301 stainless steel with a 1/2-inch stainless steel band and a carbon steel screw housing, it handles a minimum clamp diameter of 2-1/16 inches and a maximum clamp diameter of 6 inches. The quick-release mechanism allows technicians to reposition or remove the clamp without fully backing out the fastener, reducing service time during installation or maintenance. At 0.08 pounds, it is lightweight enough for overhead and confined-space work.
This clamp suits residential and light commercial service work where hose, duct, or pipe connections require a reliable, reusable mechanical seal. Typical applications include HVAC condensate drain lines, flexible duct collars, plumbing drain connections, and general-purpose hose-to-fitting attachments. The 6-inch maximum diameter range makes it versatile across common pipe and hose sizes encountered in the field. It is sized as an 88-size clamp, a standard designation that aligns with common supplier and distributor catalogs for quick cross-referencing.
Designed as an OEM-style replacement or direct-use worm-drive band clamp for hose, flexible duct, and pipe connections falling within the 2-1/16-inch to 6-inch outside diameter range.
Installation is typically performed by licensed plumbers, HVAC technicians, or pipefitters. Shut off fluid flow and relieve any system pressure before removing or repositioning an existing clamp. Seat the band fully and evenly around the hose or fitting before engaging the worm screw. Tighten until the connection is secure and leak-free, but avoid overtightening, which can deform soft hose materials or crack fittings.
