Silicone Tube Caps

A simple, reusable workshop solution designed to help keep opened sealant, adhesive and cartridge nozzles covered, cleaner and ready for their next use.

Designed and manufactured in-house by Hilltop Speed Shop, these flexible tube caps fit over compatible cartridge nozzles to help reduce exposure to air, dust, dirt and general workshop debris between uses.

Their compact push-fit design makes them quick to install and remove without relying on tape, screws or disposable coverings. Once the tube is needed again, simply remove the cap and refit it after use.

Whether you are storing a single tube at home or keeping multiple sealants and adhesives organised in a busy workshop, the available pack sizes provide increasingly better value for customers who need more than one cap.

Fitment

These caps are designed to push over compatible cartridge nozzles.

Fitment may vary depending on the outside diameter, shape and condition of the nozzle, including the amount of cured material around it.

For the best fit, ensure the outside of the nozzle is reasonably clean before fitting the cap.

The cap is intended to help cover and protect the nozzle between uses. It cannot guarantee that the contents of every tube will remain usable indefinitely, as performance will also depend on the sealant or adhesive type, storage conditions and condition of the nozzle.
