Full Product Description

Parker Veriflo division MiniButtweld™ Fittings are designed for ultra-high purity applications that require the performance and reliability of a welded tubing system. The fittings unique machining and surface enhancement prevents outgassing, inhibits corrosion, and enables installation with orbital TIG (tungsten/inert gas) welding equipment. As a result, MiniButtweld™ fittings are the go-to option for quick and easy fabrication of welded gas distribution systems.

MiniButtweld™ fittings range from 1/8 to 1/2 inch in size and come available in a variety of body configurations for use in any scenario (straight unions, tees, 90° elbows, crosses). They are specially cleaned and fabricated in a Class 100 cleanroom from Veriflo’s proprietary Vericlean™ 316L stainless steel. The 5 microinch Ra internal electropolish surface finish, provides MiniButtweld™ fittings with high corrosion resistance, and extreme cleanliness that exceeds the demands of the most stringent semicondcutor processing requirements.

The fittings’ bore diameters are matched in all sizes; thus, effectively eliminating turbulent flow, dead zones, and the risk of particle entrapment. Creation of a smoother, corrosion inhibiting flow path ensures optimal performance for any gas distribution system.
