Tweetop Press Elbow with Female Thread for PEX-al-PEX, PERT-al-PERT and EVOH pipesDesigned for every type of building, based on Tweetop PERT press fitting systemTweetop PERT pipes and fittings are also recommended for water installations. The main reason for that is the hygienic aspect of PERT material, which remains completely neutral in relation with domestic water. The second advantage is the smoothness of inner surface, both in pipes and in brass fittings, which significantly reduces the risk of forming an advantageous environment for microbes and other micro-organisms. durability estimated lifespan of min. 50 yearsenergy - saving due to low pressure losses and low thermal conductivityflexibility with no shape remembrance multilayer pipes are more flexible than any other known pipes and can be bended without any supports. Bending radius is on the level 4-5 x Dnthermal stability (0.025mm/mK) very low thermal expansion coefficient (0.025mm/mK), is comparable with values characteristic for steel or copper pipestotal impermeability of connectionspossibility of making connection with any other pipe by using threaded couplingslow weightresistance for oxygen diffusionWRAS certified

Main product features:

• Hygienic Material: Made from PERT (Polyethylene of Raised Temperature resistance), the material remains completely neutral with respect to domestic water, ensuring the highest hygiene standards.
• Smooth Inner Surface: Both pipes and brass fittings feature a smooth internal surface, significantly reducing the risk of microbial and microorganism growth.
• Durability & Lifespan: Engineered for long-term use with an estimated lifespan of at least 50 years.
• Energy Efficiency: Low thermal conductivity and low pressure losses contribute to energy savings throughout the system.
• Superior Flexibility: Multilayer construction allows for bending without the need for supports, with a bending radius approximately 4-5 times the pipe diameter (Dn)-more flexible than most known pipe types.
• Thermal Stability: Exhibits a very low thermal expansion coefficient of 0.025 mm/mK, comparable to steel or copper pipes, ensuring dimensional stability under temperature changes.
• Oxygen Diffusion Resistance: Prevents oxygen from penetrating the pipe wall, protecting system components from corrosion.
• WRAS certified
