Proseal Butt Splice Connector Jar

PROFESSIONAL QUALITY CRIMP & HEAT-SEAL BUTT SPLICE CONNECTORS

TRUSTED BY PROFESSIONALS – Master Appliance’s Proseal® butt connectors are the first choice of electricians, auto repair specialists, and other professionals who demand top-tier performance. Each connector is crimped for mechanical reliability and heat-sealed for long-lasting durability, ensuring secure, watertight connections that meet OEM standards.

ENGINEERED FOR STRONGER, CLEANER CONNECTIONS

Every Proseal® butt splice connector delivers better wire contact, less voltage drop, and superior current flow through precision engineering and quality materials. Available in three color-coded gauge sizes for easy identification:

• 10–12 AWG (Yellow)
• 14–16 AWG (Blue)
• 18–20 AWG (Red)

All connectors feature brazed seam rings and spades to prevent barrel opening and provide a stronger crimp. With 89 lbs of tensile strength and lead-free construction, Proseal® connectors maintain wire integrity and long-term reliability.

INSULATION BUILT TO LAST

Proseal® connectors feature translucent, adhesive-lined polyolefin heat-shrink tubing for easy visual inspection and corrosion prevention. Unlike lower-quality tubing, Proseal® heat-shrink tubing does not reduce in length after heating, providing superior wire support and strain relief in even the most demanding environments.

APPLICATIONS: Ideal for automotive, marine, and industrial electrical work—where watertight performance and dependable conductivity are essential.
