Unique-Bargains DR187 Electrician Tool 4.8mm Female Spade Connector Terminal Insulated Sleeve 500 Pcs

What it is and who it fits

Unique-Bargains DR187 supplies 500 clear PVC sleeves that slide over 4.8 mm female spade terminals. Electricians and automotive technicians use them to insulate crimped connections on power cables. The transparent material lets you verify the crimp and colour-code circuits without removing the cover. Each sleeve weighs about 135 g for the full pack.

What it replaces and when to upgrade

These sleeves replace worn, cracked or missing boots on existing 4.8 mm terminals. The jump is worth it when original insulation has become brittle from heat or when a harness must meet flame-retardant requirements. They also solve the problem of unidentified wires by providing a clear surface for marker pens or labels. Buyers who need a different terminal width or a non-transparent sleeve cannot use this pack.

Install ease and common pitfalls

Push the sleeve over the crimped terminal until the 3 mm end hole seats against the wire insulation; no tools are required. The soft PVC stretches slightly, so a firm hand avoids tearing the thin wall. A frequent mistake is ordering the wrong width — 4.8 mm only — which leaves loose fit on larger tabs or prevents entry on smaller ones. The +/-2 % count means you may receive a few pieces under or over 500.
