Ideal lubricant for minimal clearance valve blocks
Hetman offer a fantastic range of lubricants at varying viscosity to meet your individual needs. Nr.1 oil meets my requirements perfectly for my cornet playing. The instrument is itself new and has very marginal clearance between the piston and casing to achieve good compression. Daily application with Nr.1 oil to the pistons before and after playing has helped maintain great valve action which is both smooth and responsive.
I have used Blue Juice, Stomvi, Denis Wick, and Al Cass valve oils, but for my cornet the Hetman Nr.1 oil is the best by far. Even when not applied to the valves for several days it still remains quite effective compared to the other brands.
This is absolutely best oil for valves with close-tolerance. I have instrument made 5 years ago so valves are closely fitted. I've checked few oils but only with Hetman Nr. 1 valves are runing very fast and smooth.
