No. 2 Australian ngp LP Gas regulator AU$113with gauge adjustable up to 600 KPa = 87psi,Type 21 (=CGA510 POL) inlet for large bottles e.g. 9kg, 3/8" BSP LH outlet = A-fitting(or 3/8" inlet on demand for 2kg bottles)
The No. 2 ngp regulator is specifically adapted by an Australian company for the German Precision LP Gas Torch to go up to the setting of 600KPa and allow the torch to work to its maximum capacity, especially with the smallest tip, which has a tiny opening, so the extra pressure forces the gas through that tiny hole, offering a longer and pointier extremely precise flame and avoiding blocked tips. The regulator No 2 has a gauge, which shows the chosen pressure setting and is fully adjustable from 50KPa to 600KPa (10-90psi)
Flow rate: about 340 lpm (rated in air). In Australia by far the majority of cylinders (e.g. large 9kg LPG) have what is commonly referred to as "POL" valve
connection. It is also known as Type 21 or CGA 510, only 2kg camping gas bottles and sometimes 4.5kg have a 3/8" BSP LH fitting (More description of the different connection types on the bottom of this page)
No. 4 BOC Kayser LP Gas regulator AU$63BRNGPOL to fit Type 21 (=CGA510 POL)inlet for 4.5kg bottles or larger,
3/8" BSP LH outlet, adjustable up to 400 kPa = 58psi
The conversion rate for KPa:
1 KPa = 0.145 PSI
200 KPa : 6.895 = 29 PSI
4 – 6 Bar = 400-600 KPa = 58 – 87 PSI
for disposable LP Gas or MAPP gas cylinders:No. 2A Australian ngp LP Gas regulator AU$113
3/8" BSP LH outlet adjustable up to 400 KPa = 58psi, CGA600 inlet, To be able to use our No.2 regulator with both cylinders: An LP Gas reserve cylinder adapter FxF permits small disposable LP cylinders to be connected to the POL inlet of normal regulators or to be
used as a back-up fuel supply. Female POL x female 1"20. was offered for US$11.19 by
