What is the allowable working pressure for the Nipple 90Â° with GZ BSP for metric pipe, adjustable, stainless steel, M769LG based on tubing OD and wall thickness?

The allowable working pressure for the Nipple 90Â° with GZ BSP for metric pipe, adjustable, stainless steel, M769LG is determined by the tubing outer diameter (OD) and wall thickness. For AISI 316 metric tubing, use the manufacturerâs pressure chart (attachment referenced) to find the allowable working pressure corresponding to the tubing OD and wall thickness you have. Example guidance: - Select tubing OD (mm). - Find the specific wall thickness (mm). - Read the allowable working pressure (bar or MPa) from the chart for that OD/thickness combination. If you provide the exact tubing OD and wall thickness, I will look up and give the precise allowable working pressure for the Nipple 90Â° with GZ BSP for metric pipe, adjustable, stainless steel, M769LG.

How does tubing OD and wall thickness affect the allowable working pressure of the Nipple 90Â° with GZ BSP for metric pipe, adjustable, stainless steel, M769LG?

The allowable working pressure of the Nipple 90Â° with GZ BSP for metric pipe, adjustable, stainless steel, M769LG depends directly on two tubing dimensions: outer diameter (OD) and wall thickness. Larger OD at the same wall thickness generally lowers the allowable working pressure because the fitting must retain and seal a larger bore under internal pressure; conversely, smaller OD at the same wall thickness increases allowable pressure. Greater wall thickness for a given OD increases the tubingâs burst and allowable working pressure because thicker walls provide higher hoop strength and resistance to deformation at the fitting connection. Practically, the fittingâs rated allowable pressure is selected from a chart (per the product description and attachment) that pairs specific metric OD values with minimum required wall thicknesses; only tubes meeting or exceeding the specified wall thickness for a given OD achieve the listed allowable working pressure. Using tubing with thinner walls than specified reduces the allowable working pressure and risks leak or failure. Material (AISI 316 stainless steel) and the LET-LOKÂ® external BSP adjustable design provide corrosion resistance and reliable sealing, but they do not change the dependence: OD and wall thickness govern the mechanical pressure limit. Always consult the manufacturerâs pressure table for M769LG and verify tubing dimensions before service.
