T-Bar Coupler

SNTP T-Bar Couplers are Tapered Thread couplers which are suitable for the majority of applications of joining of the rebars. Available to suit bar sizes 12mm to 40mm,

SNTP T-Bar Couplers have a unique locking mechanism due to its self aligning thread. They are designed to achieve failure loads in excess of 125% of the characteristic strength of grade Fe 550 rebar.

They are normally fitted to the end of the threaded bar and require only the engagement and tightening of the adjoining bar on site using a Pipe wrench.

T-Bar Couplers are installed with quick and ease on site without the need for specially trained engineers or specialised, expensive machinery. The couplers are normally fitted to the end of threaded bar, requiring only the engagement and tightening of the adjoining bar on site.

SNTP T-Bar Couplers are designed for use in concrete structures to meet the requirements of IS 16172: 2014, BS EN 1992-1-1: 2004 (Eurocode 2), ACI 918 & BS 8110 for mechanical splices.

T-Bar Couplers are also compliant with BS 8597: 2015: Steels for the reinforcement of concrete.


  • The bar ends are square cut and a tapered thread is cut onto the bar.
  • Engagement of the bar within the coupler is simplified by the tapered thread design which aids alignment.
  • When the bar is fully engaged within the coupler, the continuation bar is tightened using a Pipe wrench.
  • In order to ensure correct installation, SNTP recommends the use of a torque wrench to check the tightening of the joints.
