Diversitech 7-3838 Pipe Insulation 3/8 in Id X 3/8 in Wall

Product Description

The DIVERSITECH 7-3838 is a flexible pipe insulation sleeve designed to reduce heat gain and condensation on refrigerant suction lines, chilled water pipes, and other cold-fluid piping in HVAC and plumbing systems. With an inner diameter of 0.375 inches and a wall thickness of 0.375 inches, this insulation provides meaningful thermal resistance in a compact form factor. Each section measures 6 feet in length, making it practical for standard residential and light commercial service calls. HVAC technicians and plumbers install it during new construction, system retrofits, and routine maintenance to protect piping and maintain system efficiency.

This pipe insulation is suited for residential and light commercial applications where suction line protection or condensation control is required. It fits over copper, PVC, or other pipe types with a 0.375-inch outer diameter and is commonly used in split-system air conditioning installations, mini-split linesets, chilled water distribution, and domestic plumbing where sweating pipes are a concern. The 6-foot length per piece works well for short runs and repair sections.

Key Features

• 0.375-inch inner diameter fits standard small-diameter refrigerant and plumbing lines
• 0.375-inch wall thickness provides thermal and condensation protection
• 6-foot length per section suits typical service and repair runs
• Flexible construction allows installation on existing piping without full disassembly

Compatibility

Designed as an OEM-style replacement and general-use insulation sleeve for small-diameter pipe in residential and light commercial HVAC and plumbing installations.

Installation Notes

Installation is typically performed by licensed HVAC technicians or plumbers. Shut down the system and allow piping to reach ambient temperature before applying insulation to ensure proper adhesion and fit. Slit the sleeve lengthwise if required for installation over existing pipe runs, and seal seams with appropriate insulation tape or adhesive rated for the application. Follow local mechanical and plumbing codes for insulation requirements on refrigerant and chilled-water lines.
