PUL Metric Union Elbow One Touch Fittings
The VETLEY PUL union elbow is a pneumatic one touch fitting for joining metric tubing in an elbow connection. Its engineering plastic (PBT) body is designed for pneumatic piping systems.
Sizes and pack quantity
Tube outside diameter options are 3, 4, 6, 8, 10, 12, 14 and 16 mm. Each pack contains 10 pieces of the selected size.
Selection questions
What does the PUL connector do? It connects tubing in an elbow arrangement rather than a straight union connection.
Which tube measurement should I match? Select by metric tube outside diameter, not inside diameter. The size selector is currently labelled “Outter Diamater”.
What material is listed? The product description specifies PBT engineering plastic. The earlier search description also identifies a nickel-plated zinc collar, black body and blue sleeve.
Is the operating pressure confirmed? The original text “Work Pressure:0~60°” has no pressure unit and uses a degree symbol. Do not treat it as a verified pressure or temperature rating; confirm both before use.
Why does the reference table say straight? Its old heading says “PUL Union Straight”, while this product is named Union Elbow. The heading below has been corrected to match the product name. The selector includes 3 mm, which is not listed in the reference table.
