Weld nipple with O-ring seal, tube 16 x 2 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. The data state a working pressure of 400 bar. Material stainless steel 1.4571 is listed for this version.

Benefits

• The weld seam on the 16 x 2 mm tube takes the tensile load while the O-ring does the sealing.
• The wall thickness given in 16 x 2 mm matches the 400 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 thick-walled tubes the version in stainless steel 1.4571 replaces the cutting ring, which no longer bites reliably there.
