Weld nipple with O-ring seal, tube 38 x 5 mm, stainless steel 1.4571

The weld nipple joins a precision steel tube to the coupling by a weld seam and seals with an O-ring. This version is listed with tube diameter by wall thickness 38 x 5 mm. The stated figure is a working pressure of 315 bar.

Benefits

• The weld seam on the 38 x 5 mm tube takes the tensile load while the O-ring does the sealing.
• The wall thickness given in 38 x 5 mm matches the 315 bar rating.
• The soft-sealing joint can be undone without touching the weld seam.
• The temperature range covers -20 to +200 °C.
• The version in stainless steel 1.4571 sets the corrosion protection and the suitability for welding.

Applications

On presses and hydraulic power units the welded joint carries 315 bar under changing load.
