Key specifications
Check Before You Buy
This seal is suitable if:
- Your glass is 8mm thick.
- You need a vertical seal for two straight glass panels that meet edge to edge.
- The gap between the two glass panels is approximately 3mm to 8mm.
- The glass edges are not perfectly level and a basic H-shape seal leaves a small side opening.
- You want a seal with a longer flexible fin to help improve contact between the panels.
- Your required length is 2000mm or less.
- You are fitting it to a suitable hinged or folding shower door where the seal will not obstruct the opening path.
Choose another seal if:
- Your glass is not 8mm thick.
- Your gap is smaller than 3mm or larger than 8mm.
- You need a seal for a sliding shower door.
- Your shower screen or door has curved glass.
- You are looking for a bottom seal, drip seal, threshold seal, guide rail seal or track seal.
- The seal would catch against the neighbouring panel when the door opens or folds.

Suitable Applications and Fitting Notes
The HH08 H shape shower door seal is made for 8mm glass and is used where two straight glass panels meet in a 180-degree glass-to-glass layout. It is designed to help close vertical gaps of approximately 3mm to 8mm.
This profile is useful where the two glass edges are slightly out of line. If a standard H-shape seal does not sit close enough to both panels, water may escape through the side. The HH08 uses a firm clear PVC H-shaped body to hold onto the glass, with soft flexible fins to help bridge the gap and improve the seal.
The 11mm flexible fin gives extra reach compared with shorter-fin profiles, making it a practical option for wider or less even glass-to-glass gaps within the recommended range.
In most installations, the longer soft fin should face towards the inside of the shower enclosure. This position helps direct water back into the shower area and can reduce water escaping through the vertical gap.
In some layouts, the seal may also be fitted with the fin facing outward, provided the smaller flexible fin still makes suitable contact with the opposite glass edge.
For folding and hinged shower doors, check the opening direction before cutting or fitting the seal. The profile should not sit where it may restrict movement, rub heavily or stop the door closing correctly.
This seal is not intended for sliding shower doors, curved shower glass, bottom sealing, drip sealing, shower tracks or guide rails.
