Precision Brand 20310 321 Stainless Steel Foil 0.002in X 12in X 50ft

Product Description

The PRECISION BRAND 20310 is a 321 stainless steel foil roll used in precision shimming, heat shielding, and fabrication applications across HVAC, industrial, and mechanical trades. The roll measures 0.002 inches thick by 12 inches wide by 50 feet long, providing substantial working material in a single package. Grade 321 stainless steel offers elevated resistance to intergranular corrosion and performs reliably at elevated temperatures, making it a preferred choice for applications where standard 304 stainless may not hold up. Technicians and fabricators who need thin, consistent metallic stock for gaskets, shims, or wrapping will find this roll suitable for a wide range of service work.

This foil roll is suited for use in residential and commercial HVAC installations, industrial equipment fabrication, plumbing expansion joint work, and general mechanical service. Its 12-inch width accommodates a variety of cut-to-size needs without excessive waste. The 50-foot length makes it practical for ongoing shop use or field service where multiple cuts are required. Trade professionals including HVAC technicians, pipefitters, and industrial fabricators commonly stock this type of foil for shimming, sealing, and heat barrier applications.

Compatibility

Designed as a general-purpose 321 stainless steel foil roll suitable for shimming, heat shielding, gasket fabrication, and related mechanical trade applications where thin stainless stock is required.

Installation Notes

Cut this foil using aviation snips or a metal shear rated for thin-gauge stainless steel. Wear cut-resistant gloves when handling and cutting foil stock, as edges are sharp. When used in high-temperature or pressurized service applications, follow applicable ASME, IFGC, or facility-specific codes for material suitability. Ensure all adjacent components are de-energized or depressurized before installing shim or sealing material in active systems.
