Product Benefits

  • Smooth high-strength splicing 
  • Suitable for all pipe and manhole sizes – up to 144” (3658 mm) 
  • Meets CSA A-257, BNQ 2622, ASTM C361, ASTM C443, ASTM C1619 and California Greenbook material specifications 
  • Standard and oil-resistant versions available 
  • Several profiles to meet various joint designs 

Installers love the wide, flat base that eliminates roll and twist during coupling, along with the unique wedge design, which allows for lower homing force compared to O-ring joints.

With sizes available to fit any single-offset joint configuration and multiple compounds to meet the most stringent application and soil conditions, chances are there’s an SOC gasket that’s just right for your next job.

Tylox® SOC gaskets are manufactured from synthetic rubber compounds that meet the material requirements of ASTM C1619, California Greenbook, and CSA A257.

The applicable specification is identified by a colored stripe around the periphery of the gasket:

Standard

  • C1619 Class C, C443, A257 – White stripe
  • C1619 Class A, C361, A257 – Blue stripe
  • California Greenbook – Green stripe

Oil-Resistant

  • C1619 Class D, A257 – Orange stripe
  • California Greenbook – Yellow stripe

Pressure Rating

Pipe and manholes with Tylox® SOC gaskets and single offset joints are regularly tested to the 13 psi/90 kPa requirements of ASTM C443 and C361. Higher pressures have been obtained with certain joint designs.

Tylox® SOC gaskets are produced in many different profiles to properly seal a variety of joint designs common in the pipe and manhole industries.
