Leading Tube Fittings Manufacturer, Supplier & Exporter in Oman

Mcneil Alloys is a trusted manufacturer, supplier, and exporter of precision tube fittings in Oman, delivering components engineered for safety, durability, and long-term performance. Our tube fittings are designed to create a secure, leak-free, and gas-tight connection, even in demanding operating conditions where pressure, temperature variation, and vibration are constant challenges.

Manufactured using high-grade raw materials and advanced machining processes, Our tube fittings ensure strong tube grip, consistent sealing performance, and ease of installation. The design allows fittings to be assembled, dismantled, and reassembled without compromising integrity, making them ideal for maintenance-intensive systems and critical applications.

Our tube fittings are widely used across instrumentation lines, process and control systems, analytical equipment, and fluid handling networks. They perform reliably in environments found in chemical processing units, oil & gas facilities, power generation plants, refineries, and pulp & paper industries, where operational reliability is non-negotiable. Their ability to withstand high pressure, thermal fluctuations, and mechanical stress makes them suitable for both standard and specialized industrial requirements.

Mcneil Alloys tube fittings are compatible with seamless as well as welded and redrawn tubing, including fully annealed tube types. Each fitting is manufactured with close dimensional accuracy to ensure smooth make-up, reduced risk of galling, and long service life. For projects requiring additional assurance, heat number traceability and material documentation can be provided on request, ensuring compliance with international quality and inspection standards.

With a strong export network and consistent supply capabilities, Mcneil Alloys supports industries across Oman with tube fitting solutions that balance performance, safety, and cost efficiency.
