8 mm insulated end caps for wire and hose sealing

These black silicone caps fit an 8 mm inner diameter and measure 17 x 10 mm overall. They protect screw threads, blank off alloy or silicone hoses, and insulate wire ends in automotive or general electrical work. The pack contains 100 pieces with a net weight of 54 g.

Thermal and electrical insulation in normal use

Silicone construction resists heat from engine bays and electrical loads without melting or becoming brittle. The material stays flexible across a wide temperature range, so caps do not crack or loosen under vibration. No power is drawn and no noise is generated because the parts are passive.

8 mm inner diameter decides fit

Only hoses, pipes or threads measuring 8 mm inside will seal correctly; larger or smaller bores will leak or slip. Buyers who need a different bore size must choose another listing.

Questions about this item

How do I install these 8 mm inner-diameter end caps on a hose or threaded fitting?

Slide the cap over the 8 mm inner-diameter opening until the 17 mm length seats fully against the hose or thread; the common mistake is stopping at the 10 mm outer-diameter shoulder instead of pushing to the base.

What maintenance or replacement will these silicone caps need over time?

Inspect the 100 caps periodically for cracks or hardening; silicone resists heat and oil but will eventually degrade, so replace any that lose elasticity or show splits.

What limit appears first when these caps are under sustained heat or pressure?

The 10 mm outer diameter and 17 mm length fix the sealing surface; prolonged exposure beyond silicone's temperature range causes the material to soften and lose grip first.
