The Jones Stephens JI60158 seamless rubber pipe insulation offers high-performance thermal protection for large-diameter mechanical and plumbing lines. This flexible elastomeric tube features a 1-5/8 inch inside diameter with a 3/8-inch wall thickness, designed to fit tightly over matching copper or iron pipes. With an R-value rating of 2.4, this 6-foot length segment serves as an excellent barrier against energy loss.
Engineered with a tough, closed-cell structure, this moisture-resistant rubber insulation effectively retards heat gain and prevents severe condensation or frost formation on cooling coils and cold-water systems. Mechanical installers choose this slide-on seamless product during initial piping runs due to its smooth internal talc coating that enables fast assembly. Its high cold-weather flexibility makes it resistant to tearing and rough handling under challenging job site environments.
Before installing, verify that the 1-5/8 inch physical sizing aligns correctly with your nominal copper tubing or iron pipe outer dimensions. For existing retrofits, the seamless tube can be cleanly slit lengthwise, snapped into place, and joined securely using approved contact adhesives. This elastomeric insulation provides an environmentally friendly, CFC-free solution for maximizing thermal efficiency across light commercial and residential mechanical lines.
