The narrow annular space between the jacket and the inner tube of the West condenser provides excellent cooling due to the increased flow rate of the water. The condenser has a standard taper outer joint at the top and a lower inner drip tip joint at the bottom. The hose connections have an O.D. of 10 mm at the middle serration. Available in 200-300 mm jacket lengths with 14/20, 19/22 and 24/40 joint sizes.
