French Thread TypesPopular couplings are French GAZ. These have a 24 seat and metric threads. These are similar to German DIN couplings, but the threads are different in some sizes. Although both are metric threads, the French use fine threads in all sizes and German DIN couplings use coarse threads in larger sizes. Most port connections are flange connections. French flanges are different than SAE & hellip; they have a lip that protrudes from the flange face. These are called Poclain style flanges. GAZ 24GAZ Poclain 24 FlangeGAZ 24The French Metric (GAZ) male will mate with the female 24 cone or the female tube fitting.The male has a 24 seat and straight metric threads. The female has a 24 seat or a tubing sleeve and straight metric threads.When measuring the flare angle with the seat angle gauge, use the 12 gauge. (The seat angle gauge measures the angle from the connector centerline.)MetricThread SizeMale ThreadO.D.
