Transition nipple, GZ, 28 × 3/4, bronze, B Press Gas PG4243G0280600

Gas pipe joining without compromise

The transition nipple from the B Press Gas series combines two different technologies – a bronze compression coupling on one side and a BSPT‑R gas thread on the other. This allows a quick and reliable connection of a 28 mm copper pipe to a gas installation with a 3/4 in (20 mm) thread. The straight‑line design and a 180 ° bend angle ensure easy installation even in tight spaces.

• Robust connection – bronze compression coupling (CuSn5Zn5Pb2‑C) provides a durable grip on the pipe, and the BSPT‑R thread complies with ISO 7‑1/EN 10226‑1, eliminating leak risk.
• Resistance to operating conditions – maximum working pressure 5 bar and temperature up to 70 °C make the component suitable for natural gas, LPG, and compressed air systems.
• Quick installation – the B‑profile jaw‑locking system with a yellow HNBR O‑ring featuring a PI function guarantees sealing after the first turn, without the need for additional seals.
• Compatibility – meets PN‑EN 1057 requirements, so it fits all copper pipes approved for gas installations.

Benefits for the installer and the end user

Installers value the ability to join components quickly without specialized tools, while also needing confidence that the joint will last for years of service. The bronze construction of the nipple provides corrosion resistance, and the precise manufacturing from Cu‑DHP copper (99.99 % purity) eliminates the risk of deposits inside the joint. For the end user this means:

• Safety – a leak‑tight connection protects against gas leaks.
• Longevity – 10‑year warranty and materials certified according to PN EN 1254 and PN EN 1982.
• Easy replacement – if necessary, the component can be unscrewed and replaced without damaging the pipes.

Practical applications

The product is used in:

• natural gas and LPG installations in residential and industrial buildings,
• compressed‑air systems employed in workshops and manufacturing plants,
• upgrades of existing networks where older copper pipes must be joined to modern threaded components.

Thanks to its universal size (28 mm × 3/4 in) and simple shape, the nipple is suitable for both new projects and repairs of existing installations.
