PPR C crossover with coupling
The crossover is rated PN25, with an operating temperature of 70 °C and a maximum of 95 °C, so it may be used on hot water and heating lines as well as cold water. Pressure ratings at each temperature and service life are given in the technical data sheet.

Description and application
The PPR C crossover with coupling is a socket-fusion PP-R fitting that carries one pipe over another crossing pipe in a single short C-shaped bridge, for hot and cold water lines in tight spaces. It is rated PN25 and made to EN ISO 15874-3 in Ø20, Ø25 and Ø32.
The PPR crossover with coupling is a C-shaped fitting that lets a pipe run step over another pipe that crosses its path. Installers also call it a ppr bypass bend. Its curved form makes a short bridge over the crossing line, so the run stays close to the wall or floor and fits into narrow spaces. One fitting does the job that would otherwise need several elbows and extra joints. It is made from prime-grade polypropylene random copolymer (PP-R, type 3) and conforms to EN ISO 15874-3, the standard for polypropylene fittings in hot and cold water installations. The fitting is rated PN25, with an operating temperature of 70 °C and a maximum of 95 °C. It comes in Ø20, Ø25 and Ø32 and in white, grey and green. The crossover is used in hot and cold water supply and in heating systems in homes, apartment blocks and commercial buildings. It is useful in wall chases, floor screeds and service shafts where pipes meet in the same plane. The fitting is joined by socket fusion: the pipe and the fitting are heated together on a welding machine and pushed together to form a single, permanent joint. The coupling end takes the pipe directly. It is designed to weld with THERMALINO PP-R pipes for a reliable joint and a long service life. Welding times, pressure ratings at each temperature and dimensions for each size are in the technical data sheet.

Questions
- What is a PPR crossover used for when two water pipes cross each other in the same wall chase or floor screed?
- A PPR crossover carries one pipe over another pipe that crosses its path, so both lines can stay in the same plane without clashing. The THERMALINO PPR C crossover with coupling does this with one short C-shaped bridge. It replaces a bypass built from several elbows and extra joints, which saves space in narrow wall chases and floor screeds.
- Can the PPR crossover with coupling be used on hot water and central heating lines in a residential building?
- Yes, the PPR C crossover with coupling is rated PN25 and can be used on hot water and heating lines as well as cold water. Its operating temperature is 70 °C and its maximum is 95 °C. Pressure ratings at each temperature and expected service life are given in the technical data sheet. Use them to check that the fitting suits the system's working conditions.
- How is a PPR crossover joined to PP-R pipe on site, and is it compatible with THERMALINO pipes?
- The PPR crossover with coupling is joined by socket fusion, and it is designed to weld with THERMALINO PP-R pipes. The pipe end and the fitting socket are heated together on a PP-R welding machine with heating bushes for the right size, then pushed together and held still. The result is one permanent joint with no seals or threads. Heating and cooling times for each diameter are in the technical data sheet.
- Which sizes does the PPR C crossover come in, and how do I measure a PPR pipe to choose the right one?
- The PPR C crossover with coupling is available in Ø20, Ø25 and Ø32. PP-R pipe sizes are given as the outside diameter in millimetres, so the pipe's outside diameter tells you which crossover size to choose. Measure it with a calliper, or read it from the marking printed on the pipe. The crossover comes in white, grey and green.
- What does PPR stand for, and which standard does the THERMALINO PPR crossover fitting conform to?
- PPR stands for polypropylene random copolymer, and the THERMALINO PPR crossover is made from prime-grade PP-R (type 3) to EN ISO 15874-3. That standard covers polypropylene fittings for hot and cold water installations. PP-R joints are made by heat fusion, and the material does not corrode.
