Abstract
An adapter ring which screws onto a gas tank fill fitting to cover the standard threads on the fitting and provided customized non-standard threads to prevent suppliers without matching fill hose couplings from connecting their supply hose outlet fittings to the fill fittings of tanks which they are not authorized to use. The adapter rings are fastened in place with a thread damaging member which will damage the threads on the fill fitting if there is an attempt to unscrew the adapter ring.
Claims14
In combination with a gas tank fill fitting for attachment into a tank wall, which fitting has an outwardly projecting male threaded nipple for engaging matching female threads on a retaining collar of a fill hose outlet end fitting, to hold said end fitting in operative engagement with the fill fitting, both the male and female threads being a standard size and pitch, the improvement comprising:
- (A) a customizing adapter member comprising a substantially annular body having an axially extending threaded hole therethrough with standard acme female internal threads which match the standard male threads on the nipple of the fill fitting to permit the adapter member to be screwed onto the fill fitting;
- (B) said adapter member having customized non-standard male threads on its outer circumference to prohibit the connection thereto a filler hose end fitting having a retaining collar with standard acme female threads;
- and
- (C) thread damaging means of harder material than the nipple associated with the adapter and positioned to damage the male threads on the nipple of the fill fitting when the adapter member is forcibly unscrewed therefrom and thereby render the fill fitting unusable for connecting any fill hose fitting thereto.
A customized threaded adapter for rendering a gas tank fill fitting usable only with a fill hose end fitting having a customized retaining collar with threads matching those on the adapter, said adapter comprising:
- (A) a body member having a threaded hole extending therethrough with standard acme female threads which match male threads on an outwardly extending nipple of a fill tank fitting;
- (B) said body member having an exterior male threaded portion with customized non-standard male threads which will only accept connection with a fill hose outlet end fitting retaining collar having a matching customized non-standard female threads;
- and
- (C) means to securely fasten the adapter on the fill fitting nipple so that it cannot be forcibly removed without rendering the fill fitting unusable, said means being made of harder material than the nipple.
