polypipe push fit (polyfit,polyplumb) used to come with alittle sillicone grease on the orings. They stopped it because it was easy to attract dirt onto the grease/oring and even tho they expect you to use the fittings in a clean environment its the construction game after all.
They now have "pre lubricated" dry orings but they recommend you add some polypipe sillicone grease yourself i believe if needed.
Very true 'AW' last contract I did using there gear they were pushing us to use spray lubricant,failing that the Rep said just 'gob' on them...
