Weld nipple with O-ring seal, tube 16 x 2.5 mm, phosphated steel

Once installed, the weld nipple joins a precision steel tube to the coupling by a weld seam and seals with an O-ring. The article is listed with a working pressure of 400 bar. The stated figures are tube diameter by wall thickness 16 x 2.5 mm.

Benefits

• The weld seam on the 16 x 2.5 mm tube takes the tensile load while the O-ring does the sealing.
• The wall thickness given in 16 x 2.5 mm matches the 400 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

On presses and hydraulic power units the welded joint carries 400 bar under changing load.
