Metric, blue line or PN12.5 Pipe is measured using the outside diameter (OD), given its name using the metric measuring system in metres or millimetres. Metric pipe is available with different PN (pressure) ratings and works with blue line compression fittings by Philmac and Plasson.

Installation is easy using the "Slide and Tighten" technique. Simply loosen the end nut and insert the pipe into the fitting until you feel it stop, then tighten the fitting with an adjustable wrench. Disassembly is easy because the fitting is designed so the collet is released as soon as the nut is backed off.

Philmac Poly Metric Fittings are pressure rated to 1600Kpa (PN16) to meet the needs of high or heavy static pressure.

Fittings are available to allow for direct conversion form Rural B (green line) to Metric (blue line) poly pipe as a single fitting. Due to both nut ends sharing a common thread and fitting body, the alternative inserts to suit the different poly pipe types can be achieves with the respective cap assemblies. 

Its easy, just slide and tighten! Metric fittings are pre-assembled and ready to use so there is no need to disassemble the fitting or prepare the pipe.  Simply cut the poly pipe square and slide it into the fitting until you feel the first point of resistance, then tighten the nut with an adjustable wrench or metric "c" or "y" shaped spanner.

There is no difference between the two brands, it just comes down to personal preference. Both are rated the same and use the same installation method, by unscrewing the nuts of the fitting and sliding your pipe onto the insert inside.
