Short butt-weld crosses are sanitary fittings that are manufactured in accordance with 3A standards for dimensions, tolerances, and surface finish. They are designed to direct flow in four different directions, through two lines that intersect.
Available in either 304 or 316L stainless steel.
The key difference between the 9WWWW and 9W is that the 9W is produced with tangents that are compatible with orbital/automatic welding.
