(Specification)Specification for Paintball Marker Threaded-Propellant Source Interface
Specification for Paintball Marker Threaded-Propellant Source Interface
ABSTRACT
This specification covers the male and female threaded connectors used to interface a propellant source to a paintball marker. The male connector shall incorporate a means for propellant shutoff that shall meet the maximum leakage requirement. When the male and female connectors are joined and pressurized, together they shall meet the maximum leakage specification. The male and female connector shall conform to the physical envelope described. The male connector may contain, as a means of propellant shutoff, a valve core to provide for an automatic shutoff of flow at the time of disconnection. The female connector shall have a provision for the self venting of residual gas pressure prior to the disconnection of the threaded interface.
SCOPE
1.1 This specification covers the male and female threaded connectors used to interface a propellant source with a working pressure of 10 342 kPa (1800 psig) or less to a paintball marker.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
