TBI stainless steel double seals press fit piping system is a revolutionary piping system which is leading the way in stainless steel piping in Hong Kong, Macau, China, Taiwan and Japan water supply systems. The speed at which TBI stainless steel double seals press fit piping system can be installed, the integrity of each joint, and the massive labour savings elevate TBI to an industry leading piping system. With a successful evolution from its first generation, TBI system was firstly designed in Taiwan in 2000 and further developed in Hong Kong jointly by two genius industrialists, namely Mr. Lee and Mr. Benjamin Chan, both with over 30 years pipe industry experience. TBI stainless steel double seals press fit piping system is at present the most innovative green piping system in the world. The uniqueness and precision of each fitting has lead TBI stainless steel double seals press fit piping system to be recognised as supreme in quality piping systems. Thousands and thousands of TBI fittings are being produced each year, all meeting the required quality standards. This wealth of experience means TBI have now become Hong Kong’s one of most trusted pipeline product suppliers.


TBI stainless steel double seals press fit piping technology has a 25 years guarantee on all approved applications certificated by our registered consultants, and on the other hands, manufacturers generally claim that tightness of silicone seal rings can last over 50 years.

TBI system utilized silicone rubber as sealing material which comply with BS6920:2014. No color, odor, chemical and toxic substances are released from the potable water system.
It is CHLORAMINE RESISTNACE TYPE sealing material and operating temperature range is wider (from -80℃ to +316℃ liquid state).

TBI stainless steel double seals press fit piping system can withstand very high flow rates, in excess of 40m/s. Joints are very durable and each fitting has a highly visible indicator to ensure that fittings are fixed correctly. This technology is also resistant to internal, external, and bimetallic corrosion.
