Triple vv Press Fittings
Triple(vv) Press Fittings
Rhinox Triple (VV) Press Fittings are a world-patented, 4th-generation stainless steel pipe connection system engineered for maximum leak protection, tensile strength, and long-term reliability. Featuring a unique VV-shaped double O-ring groove with 5-stage pressing across three hexagonal clamping joints, these fittings create an extraordinarily secure, pull-resistant, and permanently sealed connection — with no welding or open flame required. Manufactured in a fully automated factory with ultrasonic cleaning on every unit, they are especially suited for concealed installations behind concrete walls and underground piping where access for future maintenance is limited. Available with EPDM, HNBR, or FPM O-rings for water, gas, and high-temperature applications, the Triple (VV) system pairs seamlessly with Rhinox stainless steel pipes , Double (V) Press Fittings , and multilayer composite PEX/PERT pipes for a complete plumbing solution.
Advantage Of Installating
Triple Press Fittings
4th Generation Pipe-fit Connection
The double O-Ring bead creates a mechanical connection between pipes & fittings. The O-Ring is pressed permanently into the pipe.
Tensile Strength
Stainless steel to water pipe tensile strength is greater than 520N / mm, and has good ductility and toughness.
Pressing Jaw Guide
The Unique " 2 U-shaped slot " Jaws which guide on the fittings ensure that the pressing Jaw is positioned exactly right during pressing.
Three Hexagonal Clamping Joints
Connection position is tightly matched after mechanical compression, forming a high strength pull - resistant and sealing performance.
Minimal Liniar Expansion
This means fewer fastening points are required during installation than with conventional stainless steel plumbing.
Jewels Like Fittings
Just like jewels, each item produced by Rhinox VV press is subjected to an ultrasonic cleaning treatment.
How to Install
1
Cutting
Pipes are cut to length with approved burr-free cutters. Oxy acetylene torches and abrasive cut-off wheels are not suitable. Pipes are cut at right angles to their axis, using a pipe cutter or fine-tooth saw. Measured lengths must take into account the depth of insertion into the fitting.
2
Deburring
Make sure that the internal and external tube end is free from burrs or sharp edges by using a deburring tool to prevent damage to the O-ring. Then wipe the tube end clean to avoid damaging the O-ring on tube insertion.
3
O-Ring Checking
A patented innovatively designed 0-Ring which is available in Black = EPDM, Yellow = HNBR, Green = FPM. During the pressing, pressure is applied on fittings for 5 angles which result in a robust formation of the O-Ring bead and Before Pressing / After Pressing an extremely secure connection.
4
Marking
Marking the insertion depth: The tube must be fully inserted into the fitting until it reaches the tube stop in order to make a perfect joint. Marking insertion depth will ensure that any tube movement is detected, which is especially important if the joints are to be pressed at a later time.
5
Inserting
To assemble the joint, the tube must be inserted into the fitting up to the tube stop. Use the mark on the tube which was made earlier as reference. The pressing operation should only be undertaken when the tube reaches the tube stop.
6
Pressing
Initiate the pressing procedure by pressing the start button for approximately 3 seconds. The pressing procedure will run automatically and should not be interrupted prematurely. This ensures a permanent joint that is sealed and has the required tensional and axial force locking properties.
FAQs
Rhinox Triple (VV) Press Fittings are a world-patented, 4th-generation stainless steel pipe connection system using a VV-shaped double O-ring groove and 5-stage pressing across three hexagonal clamping joints to create a permanently sealed, pull-resistant, and torsion-proof connection — without welding or soldering.
Unlike conventional press fittings, the Triple (VV) system uses a special dual-edge safety profile with 5 pressing angles simultaneously applied. This creates a double O-ring bead mechanically pressed permanently into the pipe — delivering a higher level of sealing and mechanical locking than standard single-press systems.
They are especially recommended for concealed locations — behind concrete walls, in ceiling voids, and underground piping — where future access for inspection or maintenance is restricted, and where a failure-proof, long-lasting connection is critical.
Three O-ring options are available: black EPDM for water and heating systems, yellow HNBR for gas applications, and green FPM for high-temperature or special media applications.
The stainless steel to water pipe tensile strength exceeds 520 N/mm², with good ductility and toughness — ensuring the connection holds under high stress, pressure, and vibration conditions.
Installation follows a 6-step process: cutting the pipe squarely with a burr-free cutter, deburring the pipe end, checking the O-ring, marking the insertion depth, inserting the pipe to the tube stop, then initiating the automatic pressing procedure for approximately 3 seconds. The joint is permanently formed and cannot be interrupted mid-press.
Rhinox Triple (VV) fittings use a unique 2 U-shaped slot jaw system that guides the pressing jaw to an exact position on the fitting during pressing — eliminating misalignment errors and ensuring a consistent, correct press every time.
Yes. Every unit is produced in a fully automated factory, subjected to ultrasonic cleaning, and undergoes stringent quality testing — ensuring each fitting meets the same precision standard as the last, with zero tolerance for defects.
Triple (VV) Press Fittings exhibit minimal linear expansion, which means fewer fastening points are required during installation compared to conventional stainless steel plumbing — reducing material costs and installation time.
The Double (V) Press Fittings use a 3-point press profile suitable for standard residential and commercial applications. Triple (VV) adds a second O-ring groove and 5-stage pressing for a higher-security connection — making it the preferred choice for concealed, underground, or high-demand installations.
Yes. When considering full life cycle costs, Triple (VV) Press Fittings deliver savings through better hygiene, greater durability, reduced maintenance requirements, and competitive installation costs — making them the economical choice for projects where longevity is a priority.
