Weld nipple with O-ring seal, tube 38 x 3 mm, phosphated steel

The weld nipple joins a precision steel tube to the coupling by a weld seam and seals with an O-ring. The data sheet gives a working pressure of 315 bar. The stated figures are tube diameter by wall thickness 38 x 3 mm.

Benefits

• The weld seam on the 38 x 3 mm tube takes the tensile load while the O-ring does the sealing.
• The wall thickness given in 38 x 3 mm matches the 315 bar rating.
• The soft-sealing joint can be undone without touching the weld seam.
• The temperature range covers -35 to +100 °C.
• The version in phosphated steel sets the corrosion protection and the suitability for welding.

Applications

In hydraulic pipework the nipple joins a 38 x 3 mm tube permanently to the line.
