Warwick Hanger 1551-4 Pipe Insulation Shield 4 in

Product Description

The WARWICK HANGER 1551-4 is a galvanized carbon steel pipe insulation shield designed to protect pipe insulation at hanger contact points. Constructed from 18-gauge carbon steel with a galvanized plated finish, it fits a 4-inch pipe size with a 4.5-inch inner diameter and a 10-inch shield length. It is used by plumbers and mechanical contractors wherever insulated piping passes through hanger supports, preventing insulation compression and damage at the bearing point.

This shield is suited for residential and commercial mechanical systems where foam, fiberglass, or high-density insulation must be preserved at hanger locations. The galvanized finish provides corrosion resistance in typical indoor mechanical room and plenum environments. Each order ships in a packaging quantity of 25 shields, making it practical for new construction and retrofit piping runs with multiple hanger points.

Key Features

• 18-gauge carbon steel construction for rigid support at hanger contact points
• Galvanized plated finish resists corrosion in mechanical environments
• 4.5-inch inner diameter fits over insulation on 4-inch pipe
• 10-inch shield length distributes load across the hanger bearing area
• Compatible with foam, fiberglass, and high-density pipe insulation types
• Packaged in quantities of 25 for multi-hanger installations

Compatibility

Designed as an OEM-style insulation shield for use with standard pipe hangers on 4-inch pipe carrying foam, fiberglass, or high-density insulation in commercial and residential mechanical piping systems.

Installation Notes

Installation is typically performed by licensed plumbers or mechanical contractors following IPC and IFGC hanger spacing requirements. The shield is placed around the insulation before the hanger is tightened so the hanger bears on the steel shield rather than directly on the insulation. Inspect shield seating and ensure the insulation is not compressed beyond the shield edges before final tightening. No cutting or field modification of the shield is required for standard installations on 4-inch pipe.
