Ecm Industries Llc AMT-5123 Solder Splice 16-14 Awg 5 Pack

Product Description

The ECM INDUSTRIES LLC AMT-5123 is a 5-pack of solder heat shrink butt splice connectors rated for 16-14 AWG wire. Each connector combines a solder sleeve with a heat shrink outer jacket, creating a weatherproof, gas-tight wire splice without the need for crimping tools. When heat is applied, the solder ring melts and bonds the conductors while the shrink tubing seals the joint against moisture and corrosion. These connectors are UL Listed and suited for low-voltage wiring work in HVAC control circuits, pool and spa equipment wiring, and general electrical repair applications.

These butt splice connectors are appropriate for residential and light commercial service work where a reliable, moisture-resistant inline wire splice is required. Typical applications include field repair of thermostat wire, sensor leads, pump wiring, and control harnesses. The heat-activated solder-and-seal design is particularly useful in tight spaces or outdoor-exposed locations where a standard crimp splice would be vulnerable to moisture ingress.

Key Features

• Solder ring and heat shrink jacket activate simultaneously with a heat gun or torch
• Rated for 16-14 AWG wire gauge range
• UL Listed construction
• Creates a moisture-resistant, gas-tight splice without a crimp tool
• Sold in a 5-pack clam pack for jobsite convenience

Compatibility

Designed as an OEM-style inline butt splice connector for 16-14 AWG conductors commonly found in HVAC control circuits, pool and spa equipment wiring, and general low-voltage electrical systems.

Installation Notes

Installation is performed by licensed electricians or qualified trade technicians following NEC guidelines for wire splicing. De-energize the circuit and verify zero voltage before making any wire connections. Strip conductors to the recommended length, insert both ends into the splice, and apply heat evenly with a heat gun until the solder flows and the outer jacket shrinks uniformly. Do not use an open flame in environments where flammable materials are present.
