I Product Introduction
Brass Press Fittings for PEX-AL-PE(X) use a special (U Type) clamping tool to fix the pipe into the fitting. As a more advanced connector, it is widely used in water system, heating system, gas systems and other piping systems. In the application of aluminum-plastic pipe connection, it can play its high pressure resistance, prevent leakage, tight and other characteristics.
I Product Features
1. Quality Materials for Long-lasting Durability
Press fittings are manufactured from European standard CW617N forged brass, offering excellent corrosion resistance and mechanical strength . The forging process provides higher density and better toughness, eliminating porosity defects common in cast fittings, with strength far exceeding ordinary cast fittings.
2. Unique Design for Reliable Connections
Press fittings utilize scientific press-connection principles, using specialized pressing tools to firmly combine stainless steel or brass sleeves with pipes. This design fundamentally solves leakage problems caused by poor installation quality or material aging in traditional connection methods.
3. Quick Installation with Simple Operation
Press fitting installation requires no heat fusion equipment, no power supply, and no adhesives—only specialized pressing tools . The installation process is simple and fast: cut, insert, press, complete—each connection takes just seconds, significantly improving construction efficiency and reducing labor costs . Particularly suitable for confined spaces, job sites without electricity, and renovation projects.
4. Wide Applicability with Strong Compatibility
Press fittings are suitable for various multilayer composite pipes including PEX-AL-PEX, PERT-AL-PERT, and PEX-AL-PE. A complete range of fitting types includes couplings, elbows, tees, male/female threaded adapters, bend bridges, etc., meeting various piping layout requirements . Select models available with nickel or chrome plating for different aesthetic needs .
5. Safe and Reliable with Long Service Life
Press fittings undergo rigorous pressure testing and thermal cycling tests, with operating temperature range -20°C to 120°C and working pressure up to 10-16 bar (at 95°C) . Connection quality can be visually inspected, and systems can be pressurized immediately after installation with no curing time.

I FAQ
1. What types of pipes are press fittings suitable for?
Press fittings are specifically designed for multilayer composite pipes such as PEX-AL-PEX, PERT-AL-PERT, and PEX-AL-PE, particularly suitable for pipes with aluminum layers.
2. What is the difference between press fittings and compression fittings?
The compression pipe fittings permanently deform the sleeve using a special tool to form an irreversible and permanent connection, which is more reliable and suitable for concealed projects. The compression sleeve pipe fittings are tightened by a nut and can be disassembled and reused, making them suitable for maintenance scenarios. The compression pipe fittings have a faster installation speed and better shock resistance.
3. What special tools are needed for press fitting installation?
The main requirements are dedicated crimping tools and corresponding specifications of crimping jaws, as well as dedicated pipe cutters and calibrators. The crimping tools come in various types such as manual, rechargeable, and electric. We provide a matching installation tool kit and can offer operation training as needed.
4. How to ensure the sealing of press connections?
Press connection sealing depends on three factors: pipe cutting quality, insertion depth, and pressing quality. During installation, ensure pipe cuts are perpendicular and smooth, insertion is complete, pressing tool operation is correct, and press profiles are complete and uniform . Pressure testing after installation is recommended to verify sealing.
5. Can press fittings be reused?
Press fittings are designed for single-use connections—the sleeve permanently deforms during installation and cannot be reused . If disassembly is required, the pipe must be cut and new fittings used for reconnection. This ensures long-term connection reliability.
