Micro pipe - Internal diameter 4mm, external 6 or 7mm sometimes called 1/4". Use fittings described as either 4mm, 6mm or micro.
Supply Pipe (LDPE) - Internal diameter 13mm, external 16mm. Use fittings (barbed, quicklock or compression) described as either 13mm or 16mm.
MDPE pipe - External diameters of 16 /20 /25 /32mm. Use compression fittings described accoring to the pipe size - e.g. 25mm pipe uses 25mm fittings.
Garden Hose - 1/2" and 3/4" - use fittings described as pipe size.
Pressure and flow rates:
Bar and Pounds per Square Inch (PSI)
1 bar = 14.5PSI
10PSI = 0.69 bar
Gallons per hour(GPH) and Litres per hour (LPH)
1GPH = 4.5LPH
1LPH = 0.22GPH
Length and area.
Meters (m) and Feet (ft)
1m = 3.28ft
1ft = 0.305m
Square Meters (m2) and square yards (yd2)
1m2 = 1.2yd2
1yd2 = 0.84m2
