RHINOX Stainless steel press fitting

There are a number of possible ways to join tubes and accessories in plumbing installations, including threaded joints, welding and inseparable joints using pressfitting of accessories (such as elbows, tees, couplings, etc.).

The Rhinox Pressfitting System - V Profile is an extremely fast and simple press fitting assembly system, producing reliable joints with high mechanical resistance for a wide variety of applications, from drinking water, gas, heating and solar installations to cooling water and compressed air systems. The resilience of the deformed seal rings ensures that the fittings are permanently and hydraulically leakproof. Corrosion-resistant, stainless-steel claws on the inside of the fitting ensure high tensile strength. Pressing and insertion are quick connection methods which save a lot of time in comparison to traditional methods such as soldering or welding.

V Press Fittings

The RHINOX stainless steel installation system comprises of premium RHINOX system press fittings provided with a black EPDM sealing ring (ethylene-propylene-diene) rubber. All RHINOX press couplings are manufactured from the material coded 1.4404 / AISI 316L and 1.4408 (fittings with threaded end). The material coded 1.4404 / AISI 316L contains an increased molybdenum content of 2.3% molybdenum and a reduced carbon content, below the standard value of 1.4401. This has created a material that is not only equal in quality, but also possesses significantly greater resistance to corrosion.

RHINOX stainless steel press fittings in the 12 mm to 54 mm range are long-profile. The larger diameter material is designed with a short profile and can be fitted with an M-profile press tool only.

Seal Deformation

For permanent fittings and a high level of safety During the pressing operation, the O-ring receives a predefined deformation from the pressing jaws. During this process the gasket absorbs additional energy for a permanent and reliable seal.

Surface of the Material

A correct surface finish is necessary for more safety and longlasting hermetic seal of the system. All the weld seams are aligned perfectly with a mechanical finishing treatment for optimal sliding and perfect positioning of the gasket. Tightness of the system depends upon the roughness coefficients, much lower than the limitations prescribed by the current regulations.

Bead Geometry

There is perfect thermal execution of the weld seam. The diameters radius and wall thickness of their beads are constantly monitored in the course of production. By the help of net weld bead, on the contact surface of the gasket its being insured that the whole system is permanently sealed which also reduces the tendency to corrosion.

Mechanical Interlock

Wide range of Applications with its keen components, Rhinox system is highly resistant. An operating pressure of 2.5 MPa (25bar) and above can be achieved. Due to its highly mechanize resistant capability, wide range of superior applications are possible that surpass the most common domestic installations.

Pressing Profile

The Rhinox fittings are designed to deliver minimal deformation to the internal shape of the tube they are connecting to, reducing turbulence in the flow of the medium being conveyed. The connection provides a rigid coupling with excellent resistance totorsional forces. This is particularly beneficial when connecting mechanical threaded connections.

Tube Seam

Our Pipes are made with a homogeneous material structure. A special thermal treatment creates a homogeneous material structure in the weld seams. The seams are also smoothed mechanically. This results in the pipes and fittings behaving uniformly during the pressing operation.
