Replacement Bladder | 8L | Italian-Made

An Italian-made replacement bladder for 8L pressure water tanks — the smallest size in the bladder range, sized for compact RO holding tanks, expansion vessels on dedicated drinking-water circuits, and small system pressure-buffering applications.

When You Need an 8L Bladder

8L is the small end of pressure tank capacities. Where 12L-100L tanks handle whole-house pressurisation and commercial RO, 8L tanks typically appear in:

• Compact RO permeate storage — under-sink installations where space is tight
• Dedicated drinking-water circuit expansion — small thermal-expansion tanks on hot drinking dispensers
• Aquarium and aquaponic pressure buffering — small recirculating systems with intermittent pump cycling
• Compact pump installations — small pressure pumps where the smallest size matches the cycling characteristics

If you're replacing a bladder on an installation, the tank label model number is the most reliable identifier of size. For Bestank-Solar tanks, look for BHT-8V-S (8 litre, vertical, solar series) on the label.

What This Bladder Is

Same Italian-origin EPDM/BUTYL composite as the larger sizes in the range — just dimensioned for 8L tank shells. The material composition and certifications are identical:

• EPDM: elasticity, fatigue resistance, long pressure-cycling life
• BUTYL: gas impermeability, holds air pre-charge over years
• Drinking-water hygienic certifications by European Union and USA institutions
