Prime Line Products Sp 9712 Compression Spring 2 Pack

Product Description

The PRIME LINE PRODUCTS SP 9712 is a compression spring constructed from durable spring steel with a nickel-plated finish. Designed for general handyman and light mechanical applications, this spring measures 9/16 inch outside diameter, 29/64 inch inside diameter, and 3 inches in length with a wire diameter of 0.051 inches. The solid height is 0.954 inches and the maximum safe load rating is 19.9 pounds. The corrosion-resistant nickel plating makes this spring suitable for both indoor and outdoor use. Each package contains 2 springs. Plumbers, HVAC technicians, electricians, and general maintenance professionals use compression springs like these in valve assemblies, door hardware, panel latches, and equipment mounts.

This spring is suited for residential and light commercial maintenance applications where a small-diameter, moderate-load compression spring is needed. Common install scenarios include door hardware repair, valve stem assemblies, electrical panel components, and general equipment maintenance. The corrosion-resistant finish extends service life in humid or outdoor environments such as equipment rooms, mechanical chases, and exterior enclosures. Sold as a 2-pack, making it practical for service calls that may require a spare.

Installation Notes

Compression springs of this type are typically installed by maintenance technicians, plumbers, or HVAC service professionals during component repair or replacement. Always relieve system pressure and de-energize associated equipment before servicing any assembly containing compression springs. Verify that the replacement spring matches the original outside diameter, inside diameter, length, and load rating before installation. Avoid over-compressing beyond the solid height to prevent permanent spring set.
