United States13.2 The female connector is that connector which is configured as part of the DOT approved cylinder.4. Materials and Manufacture4.1 The male connector shall be made from materials that are compatib
15、le with CO2, compressed air or gaseous nitrogen.4.2 The O-ring seal shall be made from an elastomer compatible with CO2, compressed air or gaseous nitrogen used to powerpaintball markers. The O-ring seal shall have a hardness that will register a Type A durometer reading of between 70 to 90 6 5.The
16、O-ring shall conform dimensionally to the requirements in AMS7277 or MS28775 based upon the size and materialrecommendations of the cylinder manufacturer.4.3 The O-ring seal shall be installed on the male connector in the groove described by Dimensions C and D on Fig. 1.4.4 The male connectors shall
17、 not have any sharp edges or hanging burrs. All sharp edges will be broken R.38 MAX (R.015MAX).4.5 The male connector shall have a gas passage allowing the contents of the bottle to flow at a rate not less than 170 sL/minat 689 kPa (6 S.C.F.M. at 100 psid).4.6 This male connector is most commonly us
18、ed in paintball marker propellant applications in conjunction with SpecificationF1750.5.
