Abstract:
1. An apparatus that combines the capabilities of having a sealed access port designed to allow insertion of measurement devices and having the ability to allow for ingress and egress of trapped gasses to atmosphere comprising: a cylindrical body having a stepped outer bore and a stepped inner bore, said body having a proximal end containing threads and a distal end containing an atmospheric opening and an externally distal threaded portion, an elastomeric core, a threaded cap with retaining means to secure it to said distal end of said body, said threaded cap threadably related to said externally distal threaded portion of said body, an insert adapted to interface through a press fit with said inner stepped bore, said insert possessing a ingress end and an egress end, said egress end having an angular sealing surface and, a threaded accessory port, having a vertical axis, internal threads, having at least one exhaust passageway at an angle not coincident with said vertical axis, where said accessory port has an egress end and an ingress end for accepting said cylindrical body, and said port has an interior portion containing threads mating with said mating threads of said cylindrical body and an internal angular mating surface, said internal angular surface terminating at an angle coincident to said angular sealing surface of said insert creating an AN style of fitting, and an exterior surface, through which said exhaust passageway originates, said passageway terminating at said interior portion.
