Inconel’s remarkable strength comes from a sophisticated nickel-chromium composition, which gives these fittings their signature resistance to oxidation and extreme heat. This alloy maintains its impressive mechanical properties, including high tensile strength and excellent fatigue resistance, even when exposed to temperatures that would cause ordinary materials to weaken or break down. This inherent stability ensures that our BSP and NPT fittings provide a secure, long-lasting seal, preventing failures in critical systems where integrity is non-negotiable.
