Mueller Streamline 01421000c Insulated Suction Line 100 Ft

Product Description

The MUELLER STREAMLINE 01421000c is a pre-insulated refrigerant suction line designed for HVAC line set installations exposed to outdoor UV, weather, and physical abuse. It features Duraguard elastomeric foam insulation with a polymeric outer jacket engineered to resist solar radiation, abrasion, and moisture vapor transmission. The tube measures 7/8 inches in outer diameter with a 1/2-inch wall thickness insulation, and the coil runs 100 feet. Licensed HVAC technicians use this line in split-system installations where the suction line runs outdoors or through exposed areas requiring durable, long-term insulation performance.

This suction line is suited for residential and light commercial split-system air conditioning and heat pump installations. Its Duraguard jacket makes it a strong choice for rooftop runs, exterior wall chases, and any application where standard foam insulation would degrade from prolonged sun exposure or physical contact. The 100-foot coil length accommodates longer runs without field splicing insulation. HVAC contractors installing equipment in high-UV climates or demanding outdoor environments will find this product appropriate for those conditions.

Key Features

• Duraguard polymeric jacket provides UV, solar, abrasion, and weather resistance
• Elastomeric foam core delivers the same insulating performance as standard foam insulation
• 1/2-inch wall thickness rated R3 for thermal performance
• 5-year limited manufacturer warranty covering insulation and UV resistance
• Compliant with ASTM E-84 25/50, UL 723, ASTM C534, ASTM E96, UL 94, ASTM G153, and CA Title 24

Compatibility

Designed as an OEM-compatible suction line for residential and light commercial split-system HVAC line set applications requiring UV-resistant insulation.

Installation Notes

Installation should be performed by a licensed HVAC technician following local mechanical codes. Disconnect and lock out system power before handling refrigerant lines. Avoid kinking the copper tube during uncoiling and routing. Secure the line set per local code requirements to prevent vibration wear against structural surfaces.
