Zsi QC32 Cushion Clamp 2 Inch Tube Polyamide 150 Lb

Product Description

The ZSI QC32 is a polyamide cushion clamp designed to support, isolate, and secure 2-inch OD tubing in mechanical and plumbing installations. The cushion construction reduces vibration transfer and prevents tube wear at the contact point. Rated at 150 lb load capacity, it is suited for moderate-duty piping runs in HVAC, refrigeration, and general mechanical systems. The clamp accepts a 3/8-inch rod for standard strut or threaded-rod mounting. Its polyamide body resists corrosion and chemical exposure, making it a dependable choice in both wet and dry service environments.

Cushion clamps of this type are used in commercial and residential mechanical rooms, equipment rooms, and inline pipe runs where vibration isolation and secure tube support are required. The QC32 is appropriate for copper, steel, or plastic tubing with a 2-inch outside diameter. Typical applications include refrigerant suction and liquid lines, domestic water piping, and compressed-air distribution systems. Installation is performed by licensed HVAC technicians, pipefitters, and plumbers during new construction or retrofit work.

Key Features

• Supports 2-inch OD tubing with a cushioned contact surface to reduce vibration and abrasion
• 150 lb load capacity for moderate-duty pipe support applications
• Polyamide body offers corrosion resistance and chemical compatibility
• 3/8-inch rod diameter fits standard strut channel and threaded-rod hanger systems
• Compact, lightweight design at 0.03 pounds per clamp

Compatibility

Designed as an OEM-style replacement or new-installation cushion clamp for 2-inch OD tubing systems using 3/8-inch threaded rod or strut mounting hardware in HVAC, plumbing, and mechanical piping applications.

Installation Notes

Installation is typically performed by licensed pipefitters, plumbers, or HVAC technicians. Shut off the piping system and relieve any pressure before repositioning or replacing clamps on active lines. Secure the 3/8-inch rod to the supporting structure per applicable IPC or IFGC hanger-spacing requirements for the pipe type and size. Do not overtighten the rod fastener against the clamp body, as polyamide can crack under excessive compressive load.
