Hi-Temp Ring Terminal — 16–14 AWG / 5/16″
The Hi-Temp Ring Terminal 16-14 AWG 5/16 Stud — SKU: 9911 is a high-temperature rated ring terminal for 16–14 AWG wire, built for motorsport and performance automotive wiring where standard PVC-insulated ring terminals fail under heat exposure. The hi-temp construction maintains crimp retention, insulation integrity, and contact stability at the elevated temperatures found in race engine bays, exhaust-adjacent routing, and firewall termination points.
Why Hi-Temp Terminals Matter
Standard ring terminals use PVC insulation that softens above approximately 80–90°C. In a race engine bay, temperatures near exhaust manifolds, turbocharger housings, and cylinder heads regularly exceed this threshold. PVC at these locations shrinks, cracks, and eventually exposes bare conductors — creating short-circuit and fire risks. Hi-temp ring terminals use higher-grade insulation that maintains physical form and electrical isolation through the full thermal cycle of competitive motorsport use.
16–14 AWG — Gauge Selection
16–14 AWG handles the majority of switched power and actuator circuits in a professional motorsport harness — relay-switched loads, pump feeds, and actuator drivers all fall in this range. The 9911 crimp barrel is sized precisely for 16–14 AWG conductor cross-section, ensuring full compression across the wire bundle for maximum mechanical and electrical joint quality.
5/16″ Stud — Fixing Size
The 5/16″ stud bridges between the compact 1/4″ post and the heavy-duty 3/8″ bolt, commonly found on aftermarket battery terminals, power distribution studs, and chassis earth bars. Always confirm the stud or screw diameter at the target connection point before ordering to ensure the correct hole size is specified.
Motorsport Applications
Distribution bar connections, aftermarket battery terminal lug points, and mid-current earth strap connections where a 5/16″ stud is specified. Arctic Performance Parts stocks the full range of hi-temp ring terminal sizes covering all common motorsport gauge and fixing combinations.
