PPR Crossover with coupling
The PN25 pressure class allows this crossover to be used on hot water and heating lines as well as cold water, at an operating temperature of 70 °C and a maximum temperature of 95 °C. Permissible pressure at a given temperature and service life is listed in the technical data sheet.

Description and application
The PPR bridge bend with coupling is a Ø20 PP-R crossover fitting that lets one pipe pass over another crossing pipe in the same plane, joined by socket fusion. Rated PN25 and made to EN ISO 15874-3, it is part of the THERMALINO Eternal line for hot and cold water installations.
The PPR crossover with coupling, also known as a PPR bridge bend, solves a routine problem in plumbing and heating installations: two pipes that must cross at the same level. Its arched body carries one line over the other, so the installer does not need to build a bypass from several elbows and extra joints. The coupling end lets the fitting connect directly into the run. It is made of PP-R (polypropylene random copolymer, type 3) 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 temperature of 95 °C. It is supplied in Ø20, in white or grey, as part of the THERMALINO Eternal line. The crossover is used in drinking water distribution, domestic hot water and heating connections in homes, apartment blocks and commercial buildings, wherever pipes cross in walls, floors or service ducts. Joining is by socket fusion: the pipe end and the fitting socket are heated with a fusion tool and pushed together, forming a homogeneous joint of the same material with no seals or threads. This PPR bridge bend fuses reliably with THERMALINO PP-R pipes of the same diameter and material, giving a durable, leak-tight installation with a long service life. Values that depend on temperature and service life, such as permissible pressure, are given in the technical data sheet.

Questions
- What is a PPR bridge bend used for when two water pipes have to cross each other inside a wall or floor?
- A PPR bridge bend is used to carry one PP-R pipe over another crossing pipe in the same plane, so the lines can cross without a bypass built from several elbows. The THERMALINO crossover with coupling does this in Ø20, with a coupling end that connects directly into the run and socket fusion joints throughout.
- How is a PPR crossover with coupling joined to PP-R pipe on a domestic hot and cold water installation?
- The PPR crossover with coupling is joined to PP-R pipe by socket fusion, the same method used for all PP-R pipes and fittings. The pipe end and the fitting socket are heated together with a fusion tool, then pushed together and held until the material sets, giving a single homogeneous joint with no seals or threads. Heating times and depths for each diameter follow the fusion tool and pipe system instructions.
- Can a PN25 PPR bridge bend be used on hot water and central heating lines, and what temperatures can it take?
- Yes, the THERMALINO PPR bridge bend is rated PN25 and is suitable for hot water and heating lines as well as cold water. Its operating temperature is 70 °C and its maximum temperature is 95 °C. The permissible pressure at each temperature and service life is given in the technical data sheet and should be checked when sizing a heating system.
- Which pipes can I fuse a Ø20 PPR crossover with coupling to on a new plumbing installation?
- The Ø20 PPR crossover with coupling is fused to Ø20 PP-R pipe of matching material, and it gives a reliable weld and long service life with THERMALINO PP-R pipes. The fitting is made of PP-R (type 3) to EN ISO 15874-3. Pipes of a different material, such as PEX or copper, cannot be fused to it and need a transition fitting.
- What should an installer check to be sure PPR fittings such as a bridge bend are of good quality for drinking water systems?
- An installer should check that a PPR fitting such as a bridge bend is made of PP-R type 3 to EN ISO 15874-3 and carries a pressure class that suits the system. The THERMALINO crossover with coupling meets both points: it is made of prime-grade polypropylene random copolymer (type 3) to EN ISO 15874-3 and is rated PN25, with operating temperature 70 °C and maximum 95 °C.
