Hart Industrial O-ring Unions are engineered to provide 3000 lb. service and are the most popular union in the industry for general purpose applications.
The flat face design provides turbulence free fit across seats. This design is ideal where piping requirements dictate the necessity of having a flat face seal to make and break the pipe line.
Sockets are deep counter-bored for perfect alignment on pipe ends. Schedule 40 & 80 are standard but can be custom ordered to meet any schedule size.
All HART Unions are made in the USA.
