T-Slot Weatherstrip for 6mm Slots
This Unique-Bargains T-slot weatherstrip seal fits standard 6mm receptacles with a 7mm bulb profile. The five metre length of black silicone suits wood frame windows, casement windows and various door applications. It provides a weatherproof barrier against water, dust and noise intrusion.
Thermal and acoustic insulation properties
The silicone material delivers heat insulation and sound dampening for a quieter interior environment. Its corrosion resistant surface withstands seasonal temperature extremes while maintaining flexibility. The bulb design absorbs shock and reduces window vibration during windy conditions.
Simple cut-to-length installation
The seal installs by cutting to the required length with scissors and sliding into the T-slot receptacle. No additional adhesives, tools or fasteners are included in the package. The single piece of bulb seal covers multiple window or door frames from one continuous roll.

Questions about this item
How do I install the 5m silicone bulb seal into a 6mm T-slot, and what is the step people often get wrong?
Cut the 16.4-foot length to size with scissors, then slide the 7mm bulb straight into the 6mm receptacle; the common error is cutting the strip too short before testing the fit around the full frame.
What maintenance or replacement will this T-slot weatherstrip need over time?
The silicone resists corrosion and dust, so it only needs occasional wiping; replace the 5-meter seal if the bulb flattens permanently or cracks after years of compression.
What is the first performance limit that appears when the seal is compressed continuously in a window frame?
The 7mm bulb has relatively low elasticity, so sustained compression can cause permanent set, reducing the weatherproof and sound-insulation seal before the material itself degrades.
