COMBUSTIBLE GAS NIPPLE — safe threaded link for flammable gas service
A Combustible Gas Nipple is a threaded fitting that has to remain gas-tight in service with flammable gases such as propane, butane, acetylene and hydrogen mixtures. REAL GAZ supplies nipples suited to these duties, helping installers avoid unsuitable materials.
Material choice matters: for example, acetylene lines must not use alloys with a high copper content.

We consider EN 1442, ISO 14113 and EN ISO 7289 hose and fitting guidance, suitable for fuel gas and welding use.
Flammable gases behave differently. Propane and butane are heavier than air and collect at low points, so leaks must be detected and ventilated at floor level. Hydrogen is much lighter and escapes upward, but it passes through very small gaps. Acetylene is chemically unstable under high pressure and in contact with some metals. Each of these traits influences fitting design, which is why we check the gas before recommending a part.
Inspection routines are simple but effective. Check nipples for corrosion, thread wear and signs of over-tightening whenever equipment is serviced, replace any part that shows damage, and never reuse a fitting that has been exposed to fire. Keeping a log of inspections supports safe operation and insurance requirements.
