Wire Eyelet Ring Connector Set

Both, in that order. Strip the wire, seat it in the barrel and crimp it, then run heat over the sleeve until the tubing draws in tight and the adhesive lining flows. The crimp holds it mechanically; the sleeve seals it.

The colours are sized by gauge: Red 22–18 AWG, Blue 16–14 AWG, Yellow 12–10 AWG. 10 AWG is the largest wire these take.

Every colour comes in four: M5 #10, M6 ¼″, M8 ⁵⁄₁₆″ and M10 ⅜″. Measure the bolt or post the ring has to sit over, not the wire.

Red up to 19A, blue up to 27A, yellow up to 48A. The barrel is solid copper, so voltage drop and heat build-up stay low at those loads.

Yes, once the sleeve is properly heated. It is dual-wall tubing with an adhesive lining that melts and closes a 360° seal against the wire insulation. It is flame-retardant and rated for direct burial.

Yes, with care. A heat gun is easier to control. With a flame, keep it moving around the sleeve rather than holding it in one spot, and stop once the tubing has drawn in and the adhesive has flowed.

That is what the sealed sleeve is for. Sealed against moisture and salt, and the crimp plus solid copper barrel handle vibration and heat cycling. Keep a sensible distance from exhaust manifolds and turbos.
