WHY MASTER PROSEAL® CRIMP & HEAT-SEAL CONNECTORS BEAT OTHER BRANDS


PROFESSIONAL QUALITY CONNECTORS – Whether changing, lengthening, or repairing an electrical circuit, Master’s Proseal® connectors are built to handle any electrical project with precision and durability. Available in all the most popular sizes — 10–12 AWG (Yellow), 14–16 AWG (Blue), and 18–20 AWG (Red) — each tube is color-coded with wire gauge imprint for fast identification.
WATER-TIGHT, TRANSLUCENT DESIGN – Every Proseal® heat connector features adhesive-lined polyolefin shrink tubing for superior wire protection, visual inspection, and a contaminant-resistant seal. The tubing maintains its full length during shrinkage to ensure better insulation, wire support, and strain relief.

Each connector delivers reliable conductivity and strong mechanical support for long-lasting connections.
