Mercury Pro + Super Heavy Duty Alkaline Double Action Spray Bottle - 500ml - (EPDM Seals) pH Range: 7 to 14 (Alkaline & Heavy Bases)

The Heavy-Duty Beast Built for Strong Degreasers & High-pH Chemicals
Standard spray bottles don't last a week when faced with aggressive detailing chemicals. If you are regularly spraying heavy multi-purpose cleaners (APCs), thick citrus strip washes, or high-pH wheel cleaners, standard rubber or Viton seals will quickly swell, leak, and fail.

Enter the Kwazar Mercury Super HD Alka. Recognisable by its distinct blue trigger head and base, this sprayer is specifically engineered from the inside out to handle tough, aggressive alkaline solutions with a pH level from 7 up to 14.

Why the Mercury HD Alka is a Must-Have for Tough Jobs:

• Chemical-Grade EPDM Seals: Unlike standard bottles, the HD Alka line utilises specialised EPDM (Ethylene Propylene Diene Monomer) seals. EPDM is structurally immune to the corrosive nature of highly alkaline liquids, ensuring your spray mechanism stays smooth and leak-free month after month.
  
• Double-Action Trigger (Twin Spray Output): Cut your product application time in half. The Mercury HD Alka fires a spray both when you pull the trigger AND when you release it. You get maximum surface coverage on tyres, wheel wells, and engine bays with half the finger pumps.
  
• True 360-Degree Inverted Spraying: Spraying deep inside complex wheel spokes or underneath a vehicle chassis? No problem. The internal suction line features a weighted, highly flexible brass filter that drops wherever the liquid goes, letting you spray at any angle—even completely upside down.
  
• Adjustable Atomization: Quickly dial in your spray pattern. Go from a wide, fine mist for evenly coating massive dirty panels to a narrow, high-impact stream to blast away baked-on grime and grease from engine components.
  
• Robust, Translucent Bottle: The heavy-duty tank body is highly resistant to impact and features an embossed fluid scale in both millilitres (ml) and pints. You can mix and dilute your concentrated degreasers accurately right inside the bottle.
