Weld nipple with O-ring seal, tube 30 x 3 mm, stainless steel 1.4571

In use, 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 30 x 3 mm. It is produced from stainless steel 1.4571.

Benefits

• The weld seam on the 30 x 3 mm tube takes the tensile load while the O-ring does the sealing.
• The wall thickness given in 30 x 3 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.
