Åkes' Gas Connector Drawing Page

The following pictures are the mechanical drawings for a few DIN gas (Air and Oxygen) connector as of 1989.

All dimension in the pictures/drawing below are in [mm]. The connectors are according to the DIN 477 part 1 (200 bar) and the DIN 477 part 5 (300 bar). The threads are ISO 228-1.

Note that the Air 200 bar tank valve will accept both 200 and 300 bar regulators. The fill connector (not shown below) has a axially centred (about) 5 mm protrusion that prevents the connector from sealing in a 200 bar tank valve.

	This is the 200 bar AIR tank valve. The thread is an ISO 228-1 R5/8 pipe thread.
	The AIR regulator 200 bar connector. The thread is the R5/8. In general, an O-ring 11.3*2.4 mm (same as shown for the 300 bar below) is used instead of the sealing washer indicate din the picture. Some Swedish: Blindplugg = "Blinding plug" Tätningsring ="sealing ring"
	This is the 300 bar AIR tank valve. The Thread is an ISO 228-1 R5/8 pipe thread. (the sentence about "Ventilanslutningen skall vara..." relates to the valve to tank thread that shall be M181,5 or M252.)
	The AIR regulator 300 bar connector. The thread is the R5/8. The O-ring shall be 11.3*2.4mm
	The 200 bar DIN Oxygen tank valve connector. The outer diameter (d) shall be a Whitworth 21.8 mm 14 threads per inch, right handed. The inner diameter (0D) shall be 13 mm Some Swedish: Namn = "Name" Beteckning = "abbreviation" Ytter-diameter = "Outer diameter" Stigning, antal gängor per tum = "# threads / inch" Gäng riktning = "direction of the threads" Vänster = "Left" Höger = "Right"
