Based in Canberra, Warner Tube Fittings is your dedicated local source for precision-engineered components built to handle the toughest challenges. We specialise in supplying high-performance Inconel 718 tube fittings, offering a reliable solution for industries where failure is not an option. Our commitment is to provide not just a product, but a partnership, ensuring you have access to fittings that deliver unwavering integrity and long-lasting performance in even the most demanding environments right here in Australia.
The exceptional strength of Inconel 718 comes from its sophisticated composition, primarily nickel and chromium, with significant additions of niobium and molybdenum. This alloy is specially hardened to maintain its remarkable mechanical properties, including impressive tensile strength and excellent fatigue resistance, even when exposed to intense heat. It doesn’t soften or weaken easily, making these fittings incredibly durable and dependable under sustained stress and high-pressure conditions where ordinary materials would quickly falter.

You’ll typically find these fittings hard at work in sectors where safety and reliability are absolutely critical. They are essential in aerospace for fuel and hydraulic systems, within chemical plants handling corrosive agents, and in oil and gas extraction facing high-pressure wellheads. Their ability to perform in extreme temperatures and resist oxidation also makes them ideal for power generation turbines. Essentially, they are the go-to choice for any application demanding a connection that simply cannot afford to leak or fail.
