swapping out a Swagelok 3/8 union elbow, is this SSP Duolok one gonna match up the same?

Answer by: Customer Support on Jan 13, 2026, 6:48 AM

Interchangeability is one of the core points of the Duolok line. SSP states these fittings are totally interchangeable with the Swagelok brand of tube fittings, and this one is a 3/8 inch tube OD union 90 degree elbow.
