I Product Introduction
Brass Sliding Fittings for PEX-AL-PE(X) are connection solutions designed for PEX-AL-PE(X) multilayer composite pipes. Manufactured from high-quality forged brass, these fittings utilize sliding connection principles to achieve reliable and durable sealing. Widely used in hot/cold water supply, radiator heating, underfloor heating, and industrial piping systems, brass sliding fittings offer quick installation, reliable connections, and long service life.
I Product Features
1. Quality Materials for Durability
Sliding fittings are manufactured from European standard CW617N forged brass, offering excellent corrosion resistance and mechanical strength. The forging process provides higher density and toughness, with strength twice that of cast fittings. Material complies with drinking water hygiene standards, ensuring safe water quality.
2. Unique Design for Reliable Connections
Sliding fittings utilize axial sliding connection principles, where sliding stainless steel or brass rings tightly press the PEX-AL-PE(X) pipe onto the fitting body. The pipe itself acts as a sealing element, utilizing the molecular memory effect of PEX material to form a permanent sealed connection. This design eliminates leakage problems caused by poor installation quality.
3. Quick Installation with Simple Operation
Sliding fitting installation requires no heat fusion equipment, no power supply, and no adhesives—only specialized tools. The installation process involves just four steps: expand, insert, slide, complete—significantly improving construction efficiency and reducing labor costs. Ideal for confined spaces, job sites without electricity, and renovation projects.
4. Wide Applicability with Strong Compatibility
Sliding fittings are suitable for various multilayer composite pipes including PEX-AL-PEX and PERT-AL-PERT, with sizes covering common diameters from 16mm to 32mm. A complete range of fitting types includes couplings, elbows, tees, male/female threaded adapters, meeting various piping layout requirements.
5. Safe and Reliable with Long Service Life
Sliding fittings undergo rigorous pressure and thermal cycling tests, with working pressure up to 10bar (at 95°C) and design service life exceeding 50 years. Connection quality can be visually inspected, and systems can be pressurized immediately after installation.

I FAQ
1. Which pipes are the slip-on fittings suitable for?
They are specially designed for multi-layer composite pipes such as PEX-AL-PEX, PERT-AL-PERT, PEX-AL-PE, etc.
2. What special tools are needed for installation?
Specialized sliding tool and expander are required. We provide a matching installation tool kit.
3. How to ensure the sealing performance of the connection?
The sealing performance depends on the quality of the expansion, the insertion depth and the tightness of the ring. It is recommended to conduct a pressure test after installation: 1.5 times the working pressure, maintaining for 30 minutes without leakage is considered qualified.
4. Can the slip-on pipe fittings be reused?
They are designed for a one-time connection and cannot be disassembled and reused after installation. If disassembly is required, the pipe must be cut and a new fitting used.
5. How is the delivery time?
Inventory products will be shipped within 7 working days. Batch orders will be completed within 15-25 working days. Samples can be provided for testing.
