Unique-Bargains Insulated End Cap 1.5mm Black 100pcs

SKU CH-3TZ1-F4E64

Pack of 100 black silicone caps with 1.5 mm inner diameter protects hose ends and threaded fittings

  • Insulates wire ends with 1.5mm inner diameter
  • Protects screw threads using flexible silicone material
  • Covers hose connections across automotive and vacuum systems
  • Lightweight 18g pack supplies 100 caps for volume use
  • Compact 17mm length fits tight installation spaces

Silicone Hose End Caps

These silicone end caps fit 1.5mm inner-diameter hoses and threads. They suit automotive, plumbing or workshop tasks where open lines must be sealed quickly. The pack contains 100 pieces, giving enough spares for repeated jobs. Black colour keeps the installation discreet.

Heat-Resistant Silicone Build

Each cap measures 17mm long with a 3mm outer diameter. The flexible silicone slides over braided hose, alloy pipe or vacuum line and grips without tools. Material tolerates oil, fuel and temperature swings common in engine bays. Light weight of 18g for the full pack adds no noticeable mass.

Single-Size Limitation

Caps only seal 1.5mm bores, so larger hoses or fittings need a different diameter. They are not threaded themselves, relying on friction rather than a locking mechanism. Vibration or pressure spikes can push them off if the hose end is damaged. Buyers needing multiple sizes or positive-lock covers must source additional parts.

Questions about this item

What inner diameter does the 1.5mm insulated end cap fit?

The caps have a 1.5mm inner diameter and suit screws or hoses of that size.

What are the overall length and outer diameter of each cap?

Each cap measures 17mm long with a 3mm outer diameter (0.67 x 0.12 inches).

How are these silicone caps installed on a threaded fitting?

Push the cap straight onto the thread until the 17mm length covers the exposed end; forcing it sideways can tear the silicone.
