Water Services


Quality. Innovation. Service.

RAUTITAN water services system was developed in collaboration with industry professionals to meet the needs of designer, developer, builder and installer. Based on the advanced compression sleeve jointing technology the RAUTITAN system provides a robust, reliable and simple connection and the highest standards in hygiene, comfort and lifecycle costs. The strength and flexibility of cross-linked high-density polyethylene (PE-Xa) pipes used together with a complete range of RAUTITAN MX (DZR Brass) and RAUTITAN PX (polymer PPSU) fittings makes RAUTITAN a superior system for both residential and commercial applications. The RAUTITAN system is easier to use, faster and more economical while delivering uncompromising security, hygiene and comfort.

RAUTITAN PX. Easier. Faster. More Secure.

REHAU’s simple and secure compression sleeve joint is now even simpler. With the new easy-slide reversible sleeve you can forget about checking the sleeve end before making a joint. Made from robust, lightweight polymer (PPSU) the PX fitting weighs approximately 80% less than similar brass fittings.

The new easy-slide PX compression sleeve joint can be completed up to 20% faster with 30% less effort . With no need to check the sleeve end and the easy-slide characteristics of the joint, installations are completed quicker and simpler, with the 100% REHAU security guarantee.

The advanced polymer materials of RAUTITAN PX have been tested and engineered to meet the highest REHAU quality standards. Tough and durable, PX fittings do not display the same corrosion effects as can be seen in metal fittings, do not tend to scale and are hygienically non- hazardous – the ideal fitting for drinking water installations with the additional peace of mind against scrap-value theft.

Connection Technology

REHAU Compression Sleeve Technology

Simple. Robust. Reliable.

Over 20 years in more than 40 countries REHAU compression sleeve technology has proven over and over again to be the most secure, reliable and robust connection.
REHAU’s compression sleeve connection creates a permanently sealed mechanical joint that requires no o-rings guaranteeing a service life > 50 years.

Tested against temperature fluctuations, pressure and mechanical stresses over the long term ensure the REHAU compression sleeve technology is suitable for all conditions of heating, plumbing and gas service applications.


The quality and security of the RAUTITAN compression sleeve joint is only possible with the use of the universal and professional RAUTOOL assembly tool range. Developed specifically for the RAUTITAN system, the RAUTOOL program has been designed for the REHAU installer and is constantly being upgraded and improved by our research and development team.
Only RAUTOOL assembly tools guarantee easy installation and fully leak-proof connections. Its compact construction simplifies handling and also makes it possible to install in the toughest construction sites.

Available in a multitude of modular options, the RAUTOOL program can be tailored to the individual needs of each and every installer. Simple mechanical design and robust materials ensure long-lasting performance, minimal tool maintenance and regular calibration.
