Weld nipple with O-ring seal, tube 12 x 2.5 mm, stainless steel 1.4571

Once installed, the weld nipple joins a precision steel tube to the coupling by a weld seam and seals with an O-ring. This version comes with tube diameter by wall thickness 12 x 2.5 mm. It is complemented by a temperature range of -20 to +200 °C.

Benefits

• The weld seam on the 12 x 2.5 mm tube takes the tensile load while the O-ring does the sealing.
• The wall thickness given in 12 x 2.5 mm matches the 630 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

In hydraulic pipework the nipple joins a 12 x 2.5 mm tube permanently to the line.
