CNC Machined M4 nozzle made from POM material. Fitted with a single o-ring. POM is a strong plastic with excellent sliding properties, good resistence to grease and strong impact strength.
Our nozzles come with 2 o-rings, essentially a fat and a thin one, this gives you a choice of fitment since the outer diameter of cylinder head shafts can vary. As always please ensure you use small amount of silicone grease on the oring
