The MIDLAND INDUSTRIES 500012 is a quick-release worm-drive band clamp designed for fast, tool-assisted clamping in light industrial, plumbing, and mechanical service applications. Built from 301 stainless steel band and housing with a carbon steel screw, this clamp provides corrosion resistance and reliable clamping force in wet or chemically exposed environments. The quick-release mechanism allows rapid installation and removal without fully disassembling the clamp. It accepts a minimum clamp diameter of 0.5 inches and a maximum of 1.25 inches, making it suited for small-diameter hose, tubing, or fitting connections. The 5/16-inch bolt drive is compatible with standard hex tools.
This clamp is used in residential and light commercial settings wherever small-diameter hose or flexible tubing connections require a secure, serviceable fastening point. Typical applications include HVAC condensate drain lines, plumbing supply connections, pool equipment hose fittings, and general mechanical hose assemblies. Its quick-release design makes it a preferred choice for service technicians who need to disconnect and reconnect hose assemblies repeatedly during maintenance cycles.
Designed as an OEM-style replacement or service clamp for small-diameter hose and tubing connections in HVAC, plumbing, pool, and general mechanical assemblies requiring a worm-drive band clamp in the 0.5-inch to 1.25-inch diameter range.
Installation and removal should be performed by a qualified technician familiar with hose clamping practices applicable to the system being serviced. Always depressurize or shut off flow to the line before removing or repositioning the clamp. Use a properly sized nut driver or hex tool on the 5/16-inch bolt to avoid rounding the drive head. Do not overtighten on soft tubing materials; tighten until snug and the hose is seated without deformation.
