Sealent and Glue Tube CAPS 300g

HISTORY

When a silicone tube or glue tube is partly used it is very difficult to stop the tube slowly going off or curing in the tube.

As various methods were tried to seal the partly used tube. Taping the end, using glad wrap over the tube using the nozzle to hold it in place. Using the nozzles with the sealing cap. 

All of these methods worked for a short time, but did not provide a sufficient seal to keep the air / moisture out. 

The nozzles that are provided with the tubes in general fit loosely and don’t provide sufficient seal to stop the tube curing over time. 

SOLUTION

A cap that can screw onto the top of the partly used tube and provide an airtight would be needed.

Some investigation into the thread on the top of the tube revealed the following results;

SELLEYS – 10 Turns per inch (2.54mm pitch), thread is a half spiral. (SELLEYS CAP)

FULLER - 10 Turns per inch (2.54mm pitch), thread is a half spiral. (FULLER CAP)

SOUDAL - 10 Turns per inch (2.54mm pitch), thread is a half spiral. (SELLEYS CAP)

SIKAFLEX – 1.5mm Pitch, M15 standard thread. (SIKAFLEX CAP)

The size of the boss on the top of the tube is different between SELLEYS and FULLER. As such the cap that fits the FULLAR (larger boss) will fit onto the SELLEYS, but does not provide sufficient seal. 

The caps are a very tight fit and may seem the wrong size, but if you turn them backwards (anti-clockwise) until the thread seats, then turn clockwise with some pressure pushing the CAP on. The cap will go on. 

The caps have been labelled with the primary brand of sealant or glue that fit. 

The CAPS are a good use for all those end of spools, with only 6.1 grams per cap. 

MATERIALS

The primary material recommended for the cap is required to be water resistant. PETG, ABS and ASA would be suitable. 

For short term storage the use of PLA would be possible, however PLA does absorb water at a great rate than others.
