Zsi RPC-1-1/8 Cushion Clamp 1-1/8 in Polyamide Black

Product Description

The ZSI RPC-1-1/8 is a cushion clamp designed to secure tubing in place while absorbing vibration and reducing noise transfer. Made from black polyamide, the clamp fits a 1-1/8 inch outside-diameter tube and supports a load capacity of 175 pounds. The cushion lining protects tube surfaces from abrasion and damage during operation. This type of clamp is commonly installed by HVAC technicians, plumbers, and pipefitters to support refrigerant lines, hydraulic tubing, or similar round pipe and tube runs in both commercial and residential mechanical systems.

This clamp is suited for tube support applications where vibration isolation or surface protection is needed. It is appropriate for use in HVAC refrigerant line sets, plumbing supply lines, hydraulic systems, and general industrial tubing installations. The polyamide construction provides good chemical resistance and durability in moderate-temperature service environments. Sold individually with a minimum order quantity of one unit.

Installation Notes

Installation is typically performed by HVAC technicians, pipefitters, or plumbers during new construction or service work. Shut down and depressurize the system before installing or repositioning clamps on active lines. Ensure the clamp is mounted to a structurally sound surface using appropriately rated fasteners. Follow applicable mechanical codes for support spacing requirements for the tube material and diameter in use.
