The Solder Is Already Inside. One Heat Gun Pass and It Is Done.

Yes. The low-temp solder ring wicks into the individual wire strands through capillary action, creating a metallurgical bond. This is the same physics as traditional soldering. The difference is delivery: SolderStick puts the solder inside the connector instead of on the tip of an iron. CE certification confirm the connection meets industrial safety standards.

Any standard heat gun works. The solder melts at 138C (280F), which is well within the range of every consumer heat gun on the market. A butane torch also works if you keep it moving to avoid scorching the tubing.

A heat gun is one hand, pointed at the work from 2-3 inches away. A soldering iron requires one hand to hold the iron, one hand to feed solder, and somehow a third hand to hold the wires together. Heat guns work in any position: overhead, under a dashboard, in an engine bay. No flux. No dripping solder. No tip cleaning.

Most generic solder-seal connectors use single-wall tubing and inconsistent solder rings. Forum threads on Reddit and GarageJournal are full of reports about solder that barely melts and tubing that cracks in cold weather. SolderStick uses dual-walled polyolefin with an adhesive inner liner and is the only DTC brand with both CE certification. The $0.50 per connector price difference buys you connections that actually hold.

The kit includes all four AWG sizes, color-coded: White (26-24 AWG) for signal and speaker wire, Red (22-16 AWG) for standard automotive, Blue (16-14 AWG) for medium loads, Yellow (12-10 AWG) for high-current applications. If you are not sure, the 100-piece kit gives you enough of each size for most projects.

Every SolderStick kit ships with a 30-day money-back guarantee. If the connectors don't perform as described, return them for a full refund. no questions asked. Free worldwide shipping is included on every order.
