NOTE 2 Figure 20 (type G.50) to Figure 34 (type G.66) give the types of non-threaded outlet connections.
This document lists potentially unsafe connections where it might be possible to connect together, but which, when connected, might not be sound or secure in some operating conditions or orientations.
This document specifies a marking system that is intended to ensure that only valves and connecters that are marked with the same connector type number are used in combination.
This document also recommends tightening torques for the attachment of screwed metal-to-metal connections.
Quality assurance systems, production testing and particularly certificates of conformity are not covered in this document.
This document excludes connections for automotive vehicles covered by UN/ECE Regulation No. 67 Part 1 and EN 13760.

Ta evropski standard zajema potencialno nevarne priključke, ki jih je mogoče povezati skupaj, vendar niso trdno priključeni ali varni v določenih obratovalnih pogojih ali usmeritvah, ko so priključeni. V tem evropskem standardu je določen sistem označevanja, ki je namenjen zagotavljanju, da se skupaj uporabljajo samo ventili in priključki, ki so označeni z isto številko vrste priključka. Ta evropski standard prav tako priporoča zatezni navor za pritrditev privitih priključkov kovina-na-kovino. Sistemi zagotavljanja kakovosti, preskušanje proizvodnje in zlasti potrdila o skladnosti v tem standardu niso zajeti. Ta evropski standard ne zajema avtomobilskih priključkov iz 1. dela Uredbe UN/ECE št. 67 in standarda EN 13760. Ta evropski standard ne zajema priključkov plinskih kartuš iz standarda EN 417.

Introduction
The primary objective of this document is to ensure the safe connection of LPG cylinder valves to their
connectors.
This document is the fundamental source for identifying the essential manufacturing dimensions of the
LPG cylinder valve connections used in Europe.
EN 16129 is the fundamental source for identifying the essential manufacturing dimensions of connector
types that are not used in LPG cylinder valve connections.
This document identifies the existing cylinder valves and the connectors that are currently in use with
LPG.
It is the intention that only connections which are identified in this document should be used with LPG
cylinder valves.
1 Scope
This document specifies basic connection dimensions of LPG cylinder valves (manufactured in
accordance with EN ISO 14245 and EN ISO 15995) and connectors (including pressure regulators) to
enable them to be safely connected together.
NOTE 1 Figure 1 (type G.1) to Figure 19 (type G.33) give the types of threaded outlet connections.
NOTE 2 Figure 20 (type G.50) to Figure 34 (type G.66) give the types of non-threaded outlet connections.
This document lists potentially unsafe connections where it might be possible to connect together, but
which, when connected, might not be sound or secure in some operating conditions or orientations.
This document specifies a marking system that is intended to ensure that only valves and connecters that
are marked with the same connector type number are used in combination.
This document also recommends tightening torques for the attachment of screwed metal-to-metal
connections.
Quality assurance systems, production testing and particularly certificates of conformity are not covered
in this document.
This document excludes connections for automotive vehicles covered by UN/ECE Regulation No. 67
Part 1 and EN 13760.
This document excludes connections for gas cartridges covered by EN 417.

The dimensions shall be in accordance with those given in the following figures.
The travel distance of the valve operating mechanisms is identified where required.
The drawings show the location of sealing elements where required.
Any hexagon nut with a left hand (LH) thread shall, for easy identification, have notches (for example a
60° V groove) midway at the corners of each adjoining spanner flat. Where concentricity and surface
finish are not specified, the requirements shall be as specified by the manufacturer.
