Is CEL twisted hydraulic end, type SMZ111, light series, carbon steel compatible with O-ring seals?

Yes. The CEL twisted hydraulic end, type SMZ111, light series, carbon steel is compatible with O-ring seals only if an appropriate O-ring is used in combination with a mating component designed to accept O-ring sealing. The described design is a screwed hydraulic end with external metric thread and primary sealing on a 24Â° cone (CEL), which is a cone-to-cone metal sealing method; this means the standard sealing function is provided by the 24Â° cone contact rather than an integral O-ring groove. However, because the fitting is a screwed type intended for assembly into rubber or thermoplastic hoses using a screwed sleeve, it can be used with auxiliary O-ring seals when the mating part (e.g., a port, adaptor, or coupler) includes an O-ring groove or when an O-ring is added in a suitable recess to provide secondary or redundant sealing. Ensure the O-ring material is compatible with hydraulic fluid and operating temperature/pressure, and verify that the mating part is machined to accept an O-ring without interfering with the 24Â° cone sealing surface.
