Thread Protector Cover 3mm Black 100pcs

Unique-Bargains Thread Protector Cover 3mm Black 100pcs are silicone hose end caps designed to blank off alloy hard pipe, stainless steel braided hoses or silicone vacuum hoses. They also cover screws or other threaded fittings during storage or transport. The pack contains 100 pieces with a tolerance of plus or minus two percent.

Dimensions and Fit

Each protector measures 16mm in length with an outer diameter of 5mm, equivalent to 0.63 inches by 0.2 inches. The inner diameter is 3mm, which determines the thread or hose size it can seal. The silicone material stretches to grip the part but has a practical limit set by this fixed geometry.

Compatibility Check

Verify that the threads or hose ends you intend to cover match the 3mm inner diameter before ordering. Confirm the 16mm length is sufficient to engage the full threaded portion you need to protect. The total pack weight is 19g, so ensure your packaging or storage can accommodate 100 loose caps.

Questions about this item

Should I pick these 3 mm caps or a different diameter?

These are 3 mm inner diameter covers; choose them only when the thread or hose you need to seal measures 3 mm.

What does the 16 mm length mean once the cap is on a hose?

The cap extends 16 mm over the fitting, so it shields roughly 16 mm of exposed thread or hose end.

How does the silicone material affect the temperature range it can handle?

Silicone stays flexible from well below freezing up to typical automotive engine-bay heat, so the caps won’t crack or melt in normal use.
