“RTP” Sewage cross is used for installation of the outdoor sewerage and complies with TU 2248-002-78044889-2010 standards.

“RTP” crosses made of polypropylene and polymer copolymer are applied for the household sewerage at max. 80ºС of the permanent discharges and at 95ºС of the temporary (within 1 min.) discharges when a maximum flow level is 30 l/min. The cross is used for installation of two offsets of the main soil stack, which conveys sewers during laying of the outdoor sewer pipeline.

Rubber wiper seals with a packing block are used as gaskets, which comply with DIN 4060. An installation requires usage of “RTP” special silicone grease.
