Mastercool 93636-E 2-Way Aluminium Manifold Gauge Set 63mm R410A/R32 3×90cm

Professional 2-Way Aluminium Manifold with Free-Floating Piston Valves

Mastercool is the leading manufacturer of professional quality A/C manifold gauge sets. The 93636-E 2-way aluminium manifold gauge set features precision-machined construction, 63mm colour-coordinated gauges, and innovative free-floating piston valves that deliver superior performance and longevity. Built to last with the finest materials and machined to the highest quality standards, this is the manifold set professionals trust.

Free-Floating Piston Valves: Less Wear, Longer Life

The free-floating piston valve design is a Mastercool innovation that results in significantly less wear and tear compared to market-standard twisting piston valves. Traditional twisting valves create friction and wear with every operation — the free-floating design eliminates this problem, delivering smooth operation and extended service life.

Why This Matters: Manifold valves are operated hundreds of times during typical use. The free-floating piston design means less friction, smoother operation, and valves that maintain their sealing performance year after year. This is engineering that makes a real difference in daily use.

Double O-Ring Seal: Superior Leak Prevention

The double O-ring design provides a much better seal than single O-ring valves, resulting in fewer leaks and more reliable refrigerant containment. Each valve features two precision O-rings that create redundant sealing — if one seal degrades, the second maintains integrity. This design ensures leak-free operation even after years of professional use.

63mm Gauges: 1.6 Gauge Class Precision

The 63mm (2.5") gauges are 1.6 gauge class instruments — professional-grade accuracy for precise system diagnosis. The large dial size makes readings easy to see from any angle, whilst the colour-coordinated design allows instant refrigerant recognition. These aren't cheap import gauges — they're precision instruments built for professional HVAC work.

Colour-Coordinated for Easy Refrigerant Recognition

All Mastercool gauges are colour-coordinated for easy refrigerant recognition. The 93636-E features gauges calibrated and colour-coded for R410A, R507, R404A, and R22 refrigerants. No confusion, no mistakes — just grab the right manifold for the job.

• Piston moves linearly without rotation
• Minimal friction on seals
• Seals last significantly longer
• Smooth operation year after year
• Less maintenance, more reliability
