Polyethylene/steel transition fittings for gas and water pipe lines.

Unidelta polyethylene/steel transition fittings are designed for use in systems conveying combustible gases, water and other fluids under pressure. They are comprised of a series S5-SDR11 polyethylene stub pipe that is long enough for two electric-sleeve welds (if the first one fails) and a galvanised steel stub pipe with a threaded or welding end. The welding version is machined at the end to reduce the thickness and eliminate the zinc plating to make welding easier.

Standard diameters range from 25 mm (3/4") to 125 mm (4"). The maximum diameter of the curved version is 63 mm (2").

Polyethylene/cast iron transition fittings for water pipe lines.

Polyethylene/cast iron transition fittings can be disassembled into three parts and come with a sealing gasket. They are made of cast iron and have a female thread. The PN16-SDR7.4 high-density polyethylene stub pipe is long enough for two electric-sleeve welds if the first one fails.

Standard diameters range from 25 mm (3/4") to 110 mm (4").

Polyethylene/brass transition fittings for water pipe lines.

Polyethylene/brass transition fittings are made of brass with a male or female thread. The PN16-SDR11 high-density polyethylene stub pipe is long enough for two electric-sleeve welds if the first one fails.

Standard diameters range from 25 mm to 110 mm for the version with a male thread, and 25 mm to 63 mm for the version with a female thread.
