Product Description
The REHAU 104826-001 is a straight coupling fitting designed for use with REHAU PEX-a pipe in plumbing, radiant heating, and hydronic systems. This 1 inch by 1 inch coupling uses the EVERLOC+ compression sleeve connection system, a reliable method for joining PEX-a pipe without open flame, solvents, or crimping rings. Plumbers and mechanical contractors who work with PEX-a piping systems trust EVERLOC+ fittings for their consistent, leak-free performance in both residential and commercial applications.
The body of this fitting is constructed from polyphenylsulfone, a high-performance engineering thermoplastic known for its strength, heat resistance, and long-term durability in pressurized water systems. Polyphenylsulfone outperforms many standard fitting materials in high-temperature environments, making it a solid choice for hot and cold potable water, as well as radiant floor heating distribution systems.
Installation is straightforward for technicians familiar with the EVERLOC+ system. The compression sleeve tool compresses a stainless steel sleeve over the PEX-a pipe and fitting, creating a permanent, secure connection. No torch work is required, which speeds up installation and reduces fire risk on job sites. This fitting meets ASTM F877 and CSA B137.5 standards for SDR9 PEX pipe, and it fully complies with lead-free requirements under the US Safe Drinking Water Act, making it suitable for potable water applications across the United States and Canada.
At approximately 1.24 inches in diameter and 2.96 inches in length, this coupling is compact and fits into tight spaces common in residential rough-in and retrofit work. The straight coupling configuration connects two lengths of 1 inch PEX-a pipe in a direct, in-line orientation, making it ideal for extending runs or repairing existing pipe sections.
- Compression sleeve connection system requires only EVERLOC+ tools for fast, flame-free installation on PEX-a pipe
- Polyphenylsulfone construction provides high heat and pressure resistance for potable water and radiant heating applications
- Compliant with ASTM F877, CSA B137.5, and US lead-free drinking water requirements
