Frequently Asked Questions
How do I choose the correct plug size for my packaging tube?
Measure the outside diameter of your tube with a ruler or calliper and select the plug listed for that outside diameter. These plugs are designed to grip inside the tube wall corresponding to the stated tube outside diameter, giving a snug push-fit.
Can these round plugs be reused after removing them from the tube?
Yes, the HDPE construction and ribbed design allow the plugs to be removed and refitted multiple times under normal use. As long as the plug and tube are not damaged or excessively worn, the fit and performance should remain reliable.
Are these plugs suitable for heavy or fragile items being shipped in tubes?
The heavy duty design provides a robust closure that helps protect tube ends during normal handling and courier transit. For particularly heavy or fragile contents, these plugs should be used alongside suitable tube strength, packing materials and external packaging to ensure adequate overall protection.
