The Swagelok 316L-4TB7-9 is a 316L stainless steel tube butt weld union elbow, turning a welded tube run through 90 degrees at a 1/4 in outer diameter. Butt weld fittings of this type join by welding directly to the tube ends rather than a compression or face-seal connection, used where a permanently welded, leak-tight joint is required in a high-purity or high-integrity system.

The 316L grade (low-carbon 316) resists sensitization from weld-heat-affected zones better than standard 316 stainless steel, a standard choice for welded process tubing.
