About This Product

Threaded Flexolet

GS MetalFit provides enquiries for Threaded Flexolet fittings and related branch connection products. Olet fittings are used to form a branch connection from a run pipe or header. The correct fitting must be selected according to the required branch arrangement, thread specification, material grade, dimensions and piping design requirements.

The source catalogue identifies a broad range of material options, including stainless steel grades such as ASTM A182 F304, F304L, F316 and F316Ti; carbon steel ASTM A105; duplex and super duplex grades; and specialised alloys such as Nickel 200, Inconel 625, Monel 400 and Hastelloy C276.

The supplied information also refers to forged fittings and multiple Flexolet configurations, including threaded, socket-weld and butt-weld variants. These are separate connection options and should not be treated as interchangeable. The actual Threaded Flexolet design, thread type and manufacturing specification should be confirmed against the required drawing or project specification.

GS MetalFit can review product enquiries based on the required sizes, material, connection details, pressure class, applicable standards and inspection requirements.
