The HT Coupler is a CARES approved friction welded coupler. Hy-Ten is the exclusive UK & Ireland supplier of HT Couplers.
The HT range consists of 3 types of coupler - the HT(S) Standard Coupler and the HT(P) & HT(EP) Positional Couplers. The HT(S) type is CARES approved in diameters 12-50mm and the HT(P) & HT(EP) types are CARES approved in diameters 16-50mm.
The HT(S) is used where at least 1 bar is rotatable. The HT(P) is used where neither bar is rotatable and atleast 1 bar is moveable. The HT(EP) is used where neither bar is rotable or moveable.
All 3 types of HT Coupler can be used not only where the 2 bars are of the same diameter, but also where the 2 bars are of different diameter (i.e. transitional joints).
