DR Brass Fittings

Iplex K2® DR brass fittings are fully dezincification resistant to AS 2345 and are precision CNC machined. DR brass contains less than 15% zinc, or has been heat treated or chemically enhanced to make it resistant to the loss of zinc i.e. dezincification resistant. Brass that is not dezincification resistant can lose its zinc content leaving a residue of spongy or porous copper.

Copper Crimp Sleeves

All Iplex K2® DR brass fittings have an annealed copper crimp sleeve with a pipe depth insertion window to provide visible assurance that the pipe has been pushed fully home.

 

K2® Tooling

The crimping tools are precision instruments engineered to ensure a simple, effective joint. The principle of this jointing method has been well proven in many engineering applications in Australia. It is extensively used around the world for gas, hot and cold plumbing and in-floor heating.

With crimping tools, care should be taken to ensure that moving parts are not damaged. Refer to individual tool instructions for maintenance and correct use. Calliper gauges are supplied with all tools to check that the copper ring has been properly crimped. Only use the correct Iplex tools to crimp the Iplex K2® PE-X pipes and fittings system.

The K2® crimp tools can also be used to crimp the Iplex K1® gas system.The 16mm K2® crimp tool can be used to crimp the 18mm Pro-fit® plumbing system.  Other sizes of K2® and Pro-fit® are not compatible.
