Series 232 is a series of robust screw-to-connect couplings. The couplings are also available with teeth lock function for increased vibration resistance. Complete interchangeability with other brands following the same standard. High flow rate capacity, high quality and ability to withstand harsh conditions, make them an ideal fit for many different applications. With the teeth lock function, the connection is more vibration resistant to minimize the risk of accidental unscrewing and costly downtime.
