DYCO PPSU Cold Expansion Fittings
DYCO PPSU Cold Expansion Fittings are made from Polyphenylsulfone (PPSU) plastic specifically for PE-Xa systems and are an alternative to expensive brass fittings. PPSU fittings are lighter and resist corrosion better than metal fittings so connections are less likely to leak over time.
The DYCO Cold Expansion System concept relies on the elastic memory of the PE-Xa pipe. A DYCO cold expansion ring is fitted over the pipe end; both the pipe and ring are expanded a number of times using a recommended expander tool, then pushed onto the spigot of the cold expansion fitting.
The pipe and ring shrink back to their original state in a matter of seconds, creating a water-tight seal between the pipe and fitting. The connection between the DYCO Cold Expansion fitting and PE-Xa pipe is watertight and permanent and customers never have to be concerned about water leaks and damage to their homes or buildings.
PPSU Cold Expansion Fittings Properties
DYCO PPSU Cold Expansion Fittings Features
PPSU Fittings contain no lead making them safe for drinking water or other projects with health and safety concerns.
Significantly cheaper than metal fittings, but are long lasting and rarely need replacement and lower price fluctuations can budget project accurately.
Thanks to the chemical and mechanical properties of the material, the fitting itself can withstand greater stress and impact than the pipe the fitting is connected.
PPSU Cold Expansion Fittings are 1/5 weight of brass fittings. Lighter fittings are easier to transport, install; and much securer in the suspended piping system.
PPSU Fittings don’t need to be welded or soldered in place. They install quicker than soldered fittings reducing labour and material costs.
DYCO PPSU Cold Expansion Fittings pass impact, flexural, and vacuum performance tests according to ISO 15875-3.
DYCO PPSU Cold Expansion fittings connect pipes a permanent watertight joint in seconds with only an expansion tool.
DYCO PPSU Cold Expansion Fittings are installed without soldering, flames, or combustible gasses. Neither the fitting nor the pipe need grinding or sanding or other hazardous work & special skills.
The position pile will help plumber accurately installed the expanded ring & pipe, to make sure reach the shoulder of the fittings properly.
PE-Xa pipe is manufactured with a three-dimensional network of molecular chains making it more durable over a wide range of pressures and temperatures than other PE-Xa tubing.
Once the PE-Xa pipe compresses onto the DYCO PPSU Cold Expansion Fitting properly, the seal is permanent and no more extra sealing work is needed.
Brass and other metal fittings must be sanded to remove burrs or to fit properly within the rigid pipe. PPSU fittings and PEX pipe come ready to install and never need deburring & calibration.
