SYI Universal Flanged Adaptors, designed by experienced engineers in SYI in 2010 and applied the patent,
with wide range tolerance on O.D. (up to 24mm), SYI Universal Couplings are suitable for jointing
plain-ended pipes with same or different materials and same or different outside diameters within the
pipe O.D. ranges.

The circumferentially ribbed, specially profiled gaskets in the high quality material, provide for smooth
installation by minimizing contact friction and restrict to pull out.

The gasket also provide a leak tight seal across the O.D. range per nominal size and still allow for
thermal expansion and contraction of the pipe (up to 5mm per gasket), facilitated through gasket
deformation.

SYI Universal Flanged Adaptors , with the further more reasonable sizes and ranges, can allow the pipes of
main sizes in the most reasonable location, and the gasket can be at the perfect situation after
