Midland Industries SC-300R-SP Right Spiral Clamp 3 in

Product Description

The MIDLAND INDUSTRIES SC-300R-SP is a right-hand spiral double bolt clamp designed to secure heavily corrugated suction hoses in demanding fluid transfer applications. Constructed from steel with a zinc-plated finish for corrosion resistance, this clamp accepts a nominal 3-inch hose size with a minimum clamp diameter of 76 mm and a maximum clamp diameter of 90 mm. The bolt-drive design applies even clamping force around the full circumference of corrugated hose profiles, making it a practical choice where standard worm-gear clamps cannot seat properly. Licensed trade professionals and maintenance technicians install this type of clamp on vacuum, suction, and transfer lines across industrial and commercial settings.

The SC-300R-SP is suited for use with heavily corrugated suction hoses commonly found in industrial fluid handling, agricultural equipment, HVAC drain lines, and general-purpose liquid transfer systems. The right-hand spiral thread pattern is specific to this configuration and must be matched to the correct corresponding fitting or clamp band orientation during installation. This clamp falls in the bolt-drive, spiral double bolt category, indicating it is intended for applications requiring a secure, vibration-resistant connection on flexible corrugated hose assemblies.

Key Features

• Right-hand spiral double bolt design provides even clamping force on corrugated hose surfaces
• Nominal 3-inch hose size with a clamp range of 76 mm minimum to 90 mm maximum diameter
• Steel construction with zinc-plated finish for corrosion resistance in wet or outdoor environments
• Bolt-drive actuation allows controlled tightening with standard hand tools
• Suitable for use with heavily corrugated suction hoses where conventional clamps are not appropriate

Compatibility

Designed for use with heavily corrugated suction hoses having an outside diameter between 76 mm and 90 mm at the 3-inch nominal size. Right-hand spiral configuration must be matched to compatible hose end fittings or paired clamp components as specified by the hose manufacturer.

Installation Notes

Installation is typically performed by plumbers, industrial maintenance technicians, or fluid handling specialists. Before installing or replacing any hose clamp on a pressurized or suction line, shut off the associated pump or fluid source and relieve any residual pressure. Use the appropriate socket or wrench to tighten the bolt drive evenly and avoid over-torquing, which can distort the clamp band or damage the hose bead. Verify that the right-hand spiral orientation matches the mating component before final assembly.
