Weld nipple with O-ring seal, tube 28 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. It is supplied with tube diameter by wall thickness 28 x 2.5 mm. It is produced from stainless steel 1.4571.

Benefits

• The weld seam on the 28 x 2.5 mm tube takes the tensile load while the O-ring does the sealing.
• The wall thickness given in 28 x 2.5 mm matches the 160 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 28 x 2.5 mm tube permanently to the line.
