VERSAKRIMP 1-2 GA RING TERMINAL 5/16 BRAZED SEAM

Molex Versakrimp 1-2 GA Ring Terminal — 5/16 Brazed Seam Lug for Motorsport Primary Wiring

The Molex Versakrimp 1-2 GA Ring Terminal with 5/16 hole (19193-0309) is a heavy-duty brazed-seam crimp lug for motorsport and high-performance vehicle primary circuit terminations. At 42–53 mm² conductor cross-section with a continuous current capacity of approximately 150–170 amps, this terminal is suited to main battery cable terminations, high-capacity alternator output connections, and primary power distribution bus terminations. The brazed seam barrel construction provides a stronger, more reliable crimp joint than a simple rolled-seam barrel, maintaining electrical integrity under the vibration and thermal cycling of a race car environment.

Brazed Seam Construction

A brazed seam barrel is formed from copper that is rolled into a cylinder and then joined with a brazed filler material that closes the seam completely, creating a fully continuous cylindrical conductor. Under heavy crimp forming pressure at large wire gauges, a brazed seam barrel resists splitting — a failure mode seen with lower-quality terminals when crimping heavy conductors. The result is a tighter, more consistent crimp that reduces the risk of high-resistance joints in primary power circuits.

5/16 Hole Size — M8 equivalent

5/16-inch (M8) stud mount — suits M8 terminal studs on battery posts, MEGA fuse holders, and primary distribution blocks. Selecting the correct hole size for the target stud is essential: an undersized hole cannot be installed, while an oversized hole leaves the terminal loose on the stud even when the nut is tight, creating micro-movement under vibration that accelerates contact surface oxidation.

1-2 GA — Typical Applications

This ring terminal is suited to main battery cable terminations, high-capacity alternator output connections, and primary power distribution bus terminations. At this cable gauge, the terminal is part of the primary power circuit — the highest-current section of the vehicle’s electrical system — making a correctly specified and installed terminal critically important for both performance and safety.
