How to measure assembly

The overall length of the hose assembly is measured to the sealing surface of straight fitting or to the centerline of elbow fitting . As the following.

Length tolerance for hose assembly

Length of hose assembly	tolerance
	noninal bore diameter≤25	25< noninal bore diameter≤50	noninal bore diameter >50
assembly length<630	+7mm -3mm	+12mm -4mm	+25mm -6mm
630< assembly length≤1250	+12mm -4mm	+20mm -6mm
1250< assembly length≤2500	+20mm -6mm	+25mm -6mm
2500< assembly length≤8000	+1.5% -0.5%
assembly length>8000	+3% -1%
