Weld nipple with O-ring seal, tube 12 x 2 mm, phosphated steel

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 630 bar. This version is listed with tube diameter by wall thickness 12 x 2 mm. The stated material is phosphated steel.

Benefits

• The weld seam on the 12 x 2 mm tube takes the tensile load while the O-ring does the sealing.
• The wall thickness given in 12 x 2 mm matches the 630 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 thick-walled tubes the version in phosphated steel replaces the cutting ring, which no longer bites reliably there.
