Zsi-foster sb425 Insulated Pipe Covering Protection Saddle 4-1/4 Inch Width Black

Product Description

The ZSI-FOSTER sb425 is a black insulated pipe covering protection saddle designed for use in mechanical piping systems where copper tubing runs through strut channel support. This saddle is built to protect pipe insulation from damage at support points, a common problem in HVAC, plumbing, and refrigeration installations where insulated lines must be secured to structure without crushing or cutting through the insulation jacket. The sb425 fits copper tube sizes ranging from 2 inches up to 2.5 inches in nominal diameter, accommodating insulation outside diameters of 4.3 inches and insulation thicknesses from 1/2 inch to 1 inch. The saddle mounts directly to standard strut channel, making it compatible with the most common support systems found in commercial and industrial mechanical rooms, rooftops, and equipment rooms. Fabricated from TPV material with a painted black finish, this saddle delivers strong resistance to temperature extremes, rated for service from -50 degrees F up to 275 degrees F. That wide temperature range suits it for chilled water lines, hot water lines, refrigerant suction lines, and other insulated piping in demanding environments. The load capacity of 1200 pounds ensures the saddle can handle heavy pipe runs without deforming or failing at the support point. Meeting the UL94-HB1 flammability standard, the sb425 is suitable for installations where fire and building codes require listed or rated components. HVAC technicians, pipefitters, and plumbing contractors rely on pipe saddles like the sb425 to maintain insulation integrity, prevent condensation, and extend the service life of insulated piping systems. The 12-inch overall length and 4-1/4 inch width provide a stable bearing surface that distributes pipe load evenly across the insulation and into the strut channel support.

• Protects pipe insulation at strut channel support points, preventing crushing and moisture infiltration
• Rated for copper tube sizes from 2 inches to 2.5 inches with insulation OD of 4.3 inches
• Wide service temperature range of -50 degrees F to 275 degrees F suits chilled water, hot water, and refrigerant piping

Product Highlights

The ZSI-FOSTER sb425 delivers a 1200-pound load capacity and UL94-HB1 compliance in a TPV saddle built to preserve insulation integrity on insulated copper pipe systems mounted to strut channel supports.
