Unique-Bargains Insulated End Cap Red 5mm 100pcs

SKU CH-WZ2S-HAKA0

Red rubber caps protect 5 mm threads and tube ends, supplied in a 100-piece pack weighing 29 g

  • Red rubber caps protect threads from damage
  • 100 pieces cover large jobs or multiple projects
  • Flexible rubber moulds around irregular tubular shapes
  • Light 29 g pack is easy to store and carry
  • Fits 5 mm inner diameter screws and fittings

What it is and who it fits

These rubber caps protect 5 mm inner-diameter threads and hose ends during storage or transport. They suit mechanics, electricians and DIY users who need a quick, reusable seal for small fittings.

Limits of the push-on fit

The caps rely on friction over a 17 mm length and 6 mm outer diameter, so they stay put on clean, round threads but can slip on oily or heavily tapered surfaces. They are not rated for pressure sealing or high-temperature exposure.

Build and daily handling

Moulded red rubber weighs 29 g per hundred pieces and stretches around slightly irregular tubes without tearing. The material resists cracking in normal workshop conditions and the bright colour makes the caps easy to spot in a parts bin.

Questions about this item

Should I buy the 100-piece pack or a smaller quantity?

The listing supplies 100 caps per pack with a tolerance of plus or minus two percent; no smaller pack size is offered.

Will the 5 mm inner diameter fit my M5 threaded rod?

The inner diameter is 5 mm, matching standard M5 threads, and the rubber stretches to grip the threads securely.

What does the 17 mm length actually cover on a screw?

Each cap is 17 mm long, so it shields roughly 17 mm of exposed thread from damage and short-circuits.
