Material and Structure: The body of the pipe fittings is usually made of PP-R or PP-RCT raw materials, with pre embedded electric heating wire coils inside and external terminal posts for welding machine connection.

Temperature and pressure resistance: High quality PP-R electric melting fittings can usually withstand long-term working temperatures of around 95 ° C and working pressures of 20-25 bar (depending on specifications and wall thickness series).

Corrosion resistance and long service life: PP-R material itself is resistant to chemical corrosion, and its normal service life can reach more than 50 years.

Specification range: Common calibers range from 20mm to 250mm, with some manufacturers offering larger calibers.
