452 Series Standard Duty No Hub Coupling • Spec Sheet
Used universally in all types of construction, no-hub pipe, fittings, and couplings install quickly, absorb noise and
vibration, withstand deflection, and demonstrate corrosion resistance space-saving. Matco-Norca Standard Duty
No-Hub Couplings are particularly advantageous in compact installations and can be installed under, as well as,
above ground. Pre-fabricated units install in a fraction of the time required for conventional drain, waste vent
systems. Matco-Norca Standard Duty No-Hub Couplings are available in sizes 1-1/2” through 10”.
Standard couplings shall conform to the requirements contained in the latest edition of ASTM C1277. Shield
assembly, clamp, band, and screw housing shall be made from series 310 stainless steel and the screw made
from series 305 stainless steel. Gaskets shall comply with requirements contained in the latest edition of ASTM
C564. Standard couplings shall be marked with UPC®. These standard couplings shall be used in joining the
hubless cast iron soil pipe and fittings in a hubless cast iron sanitary system. Joints shall be tightened to the
proper torque pounds by the use of calibrated torque wrench. After installation the system shall be hydrostatically
testes to a 10 foot pounds head of water. Air testing (compressed air or gas) is not recommended. The
Neoprene gasket provides a cushioning element in the joint to absorb shock and vibration with the result of
assuring noiseless plumbing system.
