An Overview of the Rhinox-Wepit Brass Press Fittings

Rhinox Brass Press Fittings — part of the Rhinox-Wepit system — are premium non-combustible press-fit connectors engineered to work seamlessly with Rhinox Multilayer Composite PEX/PERT Pipes for fast, flame-free, and permanently sealed plumbing installations. The fitting body is manufactured in brass CW617N with nickel plating on the surface only, ensuring no contact between nickel and the fluid carried. Each fitting features a unique anti-slipping sawtooth profile hose holder, two pre-lubricated EPDM O-rings for a watertight hydraulic seal, a blue plastic collar with sight holes for insertion depth verification, and an AISI 304 stainless steel sleeve hardened to approximately 160 Hv for safe, uniform pressing. Designed for mechanical stress resistance, optimum flow performance, and visible leak detection during pressure testing, Rhinox Brass Press Fittings pair perfectly with stainless steel pipes , Double (V) Press Fittings , and Triple (VV) Press Fittings for a complete Rhinox plumbing system.

Brass CW617N Used for Designing the Fitting’s Body

The body of the Rhinox press fittings is made of brass nickel. Note that the nickel plating only remains on the surface and does not have any contact with the fluid carried. The body comprises mainly two parts – one is visible while the other enters the tube. The latter one is referred to as the hose holder. It features a unique anti-slipping sawtooth profile and houses two O-rings that ensure a proper hydraulic seal.

Seals in the O-Rings

Each end of the fitting enters the pipe. The ends are equipped with two pre-lubricated EPDM O-rings. They ensure a watertight seal. Evidently, they can accommodate the different expansion rates of the materials used in the system. If the pressing is incorrect or incomplete, the fitting may leak visibly during the testing phase.

Bush Holder Ring

The prime USP of the Rhinox press fittings is that they feature a blue plastic collar that comes with sight holes. This feature facilitates proper installation. Through the sight holes, the installer will know that the pipe is inserted completely into the fitting before the pressing phase.

Stainless Steel Sleeve

The AISI 304 grade stainless steel sleeve is marked with the thickness of the corresponding pipe, diameter, and the pressing profile, which are U, H, and TH. It is produced by a drawing process that ensures ~ 160 Hv hardness for safe and uniform pressing.

Rhinox-Wepit System – A Few Technical Features

Rhinox-Wepit System has some excellent technical features. The following are the technical features of the Rhinox-Wepit System:

Visible Leakage

Unpressed or defective parts that connect with one another may have visible leaks. So, during pressure testing with water, these leaks will be visible. So installers can easily identify and address these leaks and ensure an accurate and reliable installed system.

Seamless and Easy Installation

The combination of the Sawtooth and retaining rings present on the brass fittings helps achieve a higher retention force in the fitting within the pipe. This prevents the fitting from slipping out during the installation phase. Such a design facilitates seamless alignment and pressing, thereby improving the installation process.

Insertion Depth Control

The insertion depth in the Rhinox press fittings is always visible. This ensures that the pipe is pushed out correctly onto the fitting while installing. This feature allows for the system to be pre-mounted. Moreover, it easily allows for verifying every connection and its position before they are ready to press.

Mechanical Stress Resistant

Rhinox press fittings feature innovative design, intuitive installation features, and a safe sealing mechanism. So, it improves their ability to withstand sudden mechanical shocks and loads, thereby offering stability under challenging conditions.

Optimum Flow

When it comes to the piping system, reliability and optimal performance are significant. The Rhinox-Wepit fittings come with a larger inner bore, which is advantageous for pipes having smaller diametres. Note that the impact of the inner bore is most significant on pressure loss. The feature ensures that customers can enjoy effective flow performance and maximise the potential of the fitting range.

We have built a new design of brass fittings with the above features that offer stability and durability during demanding conditions. Seek consultation from us to learn more about our fittings.

FAQs

Rhinox Brass Press Fittings are non-combustible, press-fit pipe connectors from the Rhinox-Wepit system. They are designed to work with Rhinox Multilayer Composite (MLC) PEX/PERT Pipes and use a stainless steel sleeve compressed by a press jaw to create a permanent, watertight, and mechanically secure joint — with no welding, soldering, or open flame required.
The fitting body is manufactured from brass CW617N with a nickel-plated surface finish. Importantly, the nickel plating only covers the external surface and has no contact with the fluid being carried through the pipe — ensuring full hygiene and water safety.
The hose holder is the internal part of the fitting that enters the pipe. It features a unique anti-slipping sawtooth profile that creates a high retention force, preventing the fitting from slipping out during installation. It also houses two pre-lubricated EPDM O-rings that form the hydraulic seal.
Each end of the fitting is equipped with two pre-lubricated EPDM O-rings that ensure a watertight hydraulic seal. The O-rings are designed to accommodate the different expansion rates of the materials in the system, maintaining seal integrity across varying temperatures and pressures.
The blue plastic collar is fitted with sight holes that allow the installer to visually confirm that the pipe has been fully and correctly inserted into the fitting before pressing begins. This eliminates guesswork, enables pre-mounting verification, and ensures every connection is correctly positioned before it is permanently pressed.
The sleeve is manufactured from AISI 304 grade stainless steel using a drawing process that achieves approximately 160 Hv hardness. It is marked with the corresponding pipe thickness, diameter, and pressing profile (U, H, or TH). The sleeve is compressed by the press jaw to permanently lock the pipe into the fitting during installation.
If any connection is unpressed or defectively pressed, it will produce a visible leak during water pressure testing. This built-in safety feature allows installers to quickly and reliably identify and fix any faulty connections before the system goes live — ensuring a completely reliable installed system.
The insertion depth of the pipe into the fitting is always visible through the sight holes in the blue plastic collar. This ensures the pipe is pushed fully and correctly into the fitting, allows the system to be pre-mounted, and enables every connection to be verified before pressing — reducing installation errors significantly.
Rhinox Brass Press Fittings feature a larger inner bore compared to standard press fittings, which is particularly advantageous for smaller diameter pipes where bore size has the greatest impact on pressure loss. This ensures optimum flow performance and maximum system efficiency throughout the plumbing installation.
Yes. The innovative design, intuitive installation features, and secure sealing mechanism of Rhinox Brass Press Fittings make them highly resistant to sudden mechanical shocks and loads — ensuring stability and performance even under challenging installation and operational conditions.
Rhinox Brass Press Fittings are primarily designed for use with Rhinox Multilayer Composite (MLC) PEX/PERT Pipes . They form part of the complete Rhinox-Wepit system, which can also be integrated with stainless steel pipes and Rhinox press fitting systems for hybrid plumbing layouts.
