What It Is

The Unique-Bargains Insulated End Cap is a black silicone cover designed to protect wire ends, screw threads and hose openings. Each cap measures 17 x 7mm overall with a 6mm inner diameter. The pack contains approximately 100 pieces weighing 41g in total.

What The Pack Changes

Having 100 caps on hand lets you seal multiple hoses, pipes or threaded fittings in a single job without reordering. The silicone material resists heat and chemicals, so the caps stay flexible on stainless braided lines, alloy hard pipe or vacuum hoses. The black colour gives a uniform look across all covered ends.

Who It Suits

Mechanics and DIYers who need a bulk supply of small-diameter caps for automotive, marine or industrial plumbing will find the quantity practical. Buyers who need larger diameters, different colours or only a few pieces should look at something else.

Questions about this item

Will the silicone caps degrade and need replacing after long-term heat exposure?

The caps are made from silicone rubber that resists heat and oil, so they do not have a scheduled replacement interval under normal automotive use.

What is the maximum hose diameter these 6 mm inner-diameter caps can seal before they stretch too far?

Each cap fits a 6 mm inner diameter; stretching beyond that will reduce the seal and is not recommended.

Do the caps get hot or soft when left on engine-bay hoses all day?

Silicone remains stable at typical under-hood temperatures and the 41 g total pack weight adds negligible thermal mass.
