Our engineers reimagined the construction of the Needle Packing. The result is a build which takes away all the guesswork of how to tighten it properly. Simply tighten it and everything else is being taken care of.

The inverted design of Anest Iwata’s recent Air Valve Seat Sets was already sealed by a solvent resistant O-Ring, which makes it very durable and less prone to over tightening. Now we have taken this already proven design and have made it from a piece of Aluminum.
