{"product_id":"the-solderless-closed-end-crimp-caps","title":"The Solderless | Closed-End Crimp Caps for Automotive and Marine Wiring","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003eA wire joint is never the interesting part of a build. It is the part that decides whether the build survives. Every harness, every amplifier feed, every trailer light that quits on a wet Tuesday traces back to one connection that was made in a hurry.\u003c\/p\u003e\n\u003cp\u003eThese closed-end caps answer that problem with the oldest logic in electrical work. Twist the conductors, push them into the aluminium barrel, close the crimp. The plastic sleeve then seals the whole joint into a single insulated body, so nothing bare is left for moisture, salt or vibration to find. There is no flame, no flux, no melted insulation, and no waiting for a soldering iron to come up to temperature in a cold garage.\u003c\/p\u003e\n\u003cp\u003eThe assortment covers the three sizes that handle nearly all low-voltage work. CE1 takes the thin gauge used in signal and lighting runs, CE2 handles the common 18 to 14 AWG range, and CE5 takes heavier audio and power leads. Order them at fifty, one hundred or one thousand pieces and the kit scales from a single repair to a production bench. The aluminium insert bites into copper instead of sitting on top of it, which is what separates a joint that lasts a decade from one that loosens after a season.\u003c\/p\u003e\n\u003cp style=\"font-style:italic; color:#1a3a5c; border-left:3px solid #c9a227; padding-left:14px; margin-top:22px;\"\u003eNobody photographs a crimp cap.

The barrel has to swallow the full bundle of twisted conductors with the insulation stripped back far enough that no plastic sits inside the metal. If the bundle will not seat, forcing it deforms the sleeve and the joint loses its seal. Step up a size instead.\u003c\/p\u003e\n\u003cp\u003eA simple rule works in practice. Use CE1 for signal and lighting runs in the thin gauge range, CE2 for the everyday 18 to 14 AWG work that fills most harnesses, and CE5 for heavier audio power and accessory feeds. A mixed stock of all three covers a full vehicle without a second order.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-specs\" style=\"margin-top:26px;\"\u003e\n\u003ch3 style=\"font-size:19px; color:#1a3a5c;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul style=\"list-style:none; padding:0; margin:12px 0;\"\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Closed-end crimp cap \/ pigtail connector\u003c\/li\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e CE1, CE2, CE5\u003c\/li\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003eBody material:\u003c\/strong\u003e Plastic sleeve with aluminium insert\u003c\/li\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003eConnection method:\u003c\/strong\u003e Twist, insert, crimp\u003c\/li\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003ePack quantities:\u003c\/strong\u003e 50, 100 and 1000 pieces\u003c\/li\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e CE, RoHS\u003c\/li\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003eWire type:\u003c\/strong\u003e Stranded and solid copper\u003c\/li\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003eTypical gauge range:\u003c\/strong\u003e 22 AWG to 10 AWG depending on size\u003c\/li\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003eOperating environment:\u003c\/strong\u003e Automotive, marine, indoor and sheltered outdoor\u003c\/li\u003e\n\u003cli style=\"padding:8px 0; border-bottom:1px solid #eeeeee;\"\u003e\n\u003cstrong\u003eInsulation:\u003c\/strong\u003e Fully enclosed after crimping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-applications\" style=\"margin-top:26px;\"\u003e\n\u003ch3 style=\"font-size:19px; color:#1a3a5c;\"\u003eWhere It Belongs\u003c\/h3\u003e\n\u003cp\u003eAudio installers reach for these when a head unit has to be swapped without cutting the factory harness.
