Reliable homogeneous connections
Homogeneity melting provides reliable connection strength and sealing property between PP-R pipes and PP-R fittings.



Metal thread connection

Rifeng also provides metal thread connection methods to achieve connection conversion between different scenarios. 

Rifeng PP-R fittings have an unique structure - swallow tailed structure on the metal insert, which can eliminate the risk of leakage from gaps caused by different thermal conductivity performances of brass and plastic.
Rifeng holds the exclusive patent to manufacture these fittings.
