High Quality Solid BRASS adaptors
PROPANE BOTTLE ADAPTOR
NRV -stands for NON RETURN VALVE
This is Bayonet type adaptor (to refill in UK or Netherlands) for
other country adaptors please check our store
NOTE! There are two types of valves on red bottles MALE and FEMALE
(please refer to pictures for explanation)
this adaptor WILL FIT BOTTLES with FEMALE entry
For professional use only
!!! WARNING !!!
Bottles must undergo pressure tests from time to time at refilling plants
Dont forget to exchange your bottles with main supplier every year if possible
!!! Beware of Steel or Metal copies !!!
Why you shouldn't buy cheap Steel or Metal copies?

What is Brass?
Brass is the broad term for a range of copper-zinc alloys. Depending on the composition, the physical properties of the metal can vary. This includes strength, machinability, ductility, wear-resistance, hardness, colour, anti-microbial, electrical conductivity, thermal conductivity and corrosion resistance.
Two qualities, the ability to form castings and great machinability, make brass the perfect choice for manufacturing precision valves and fittings.
What Makes Brass Good for LPG?
Sparks generated by “friction” can commonly occur when other metals impact on each other or on other materials such as steel or concrete. A mechanical or frictional spark is generated.
Unlike ferrous metals – metals containing Iron – which will generate sparks upon impact, brass does not spark on impact. Brass is considered to be "non-sparking".
Brass also tolerates low temperatures. This is important because LPG vaporisation can cause gas bottles and valves to become very cold. Brass does not become brittle at low temperatures, unlike mild steel.

Avoiding Sparks
The need to avoid sparks in a flammable environment, such as around LPG gas vapour, is easy to understand. The fact that brass does not spark makes it ideal for the coupling of LPG valves and hoses. The perfect everyday examples are BBQ gas valves, regulators and autogas filling guns.
During the connection of these common LPG fittings, it is not at all unusual for the fittings to bang into each other. Being made from brass means that these impacts do not generate any sparks, preventing possible ignition, if flammable gas vapour were to be present.

========================================================================
Bottle MUST be EMPTY if no 80% shut off valve fitted
CONNECT ADAPTER & FILLING GUN
OPEN BOTTLE VALVE & FILL
SHUT BOTTLE VALVE FIRST then REMOVE GUN
instructions and volumes are printed on the side of adaptor.
use of gloves highly recommended
If you don't know how to use it,
please don't buy it
This adaptor may be used with gas bottles
with LEFT HAND 5/8" thread fitting. Please refer to pictures.
INSIDE bayonet there is also M21.8 thread Right Hand
which can be used for additional adaptors from our store so you can fill up anywhere in EU
Thank you for shopping with British based company
