Tylox® “CF” Series Pipe Gasket

Standard and Oil-Resistant versions available

Contoured-fin, Profile Gaskets for Single-Offset Concrete Pipe

 

Tylox® CF Gaskets are designed for higher pressure sealing applications for concrete sewer pipe. The unique contoured-fin, and pressure pocket design allows for water-tight sealing of up to 42 ft (18 psig) of infiltration pressure.

Benefits of the Tylox® CF contoured-fin gasket

  •  Unique cross-section virtually eliminates “Roll-Back”. The approach-slope design of the contoured fin gasket acts to self-center the spigot as it enters the bell, assuring a more even alignment and eliminating gasket twist and roll-back. Pipe homes more smoothly and easily.
  •  Integral pressure pocket withstands water ingress up to 42 ft head (18 psig or 125kPa). The unique pressure pocket design functions as a self-energizing pocket, allowing the gasket to effect greater sealing pressure as infiltration pressure increases.
  •  Colored-Stripe on leading edge ensures correct positioning.
  •  Design allows up to a 1/2” of joint deflection without leaks.
  •  The contoured fin lip-seal allows for greater bell and spigot tolerance variation than “O” ring-style gaskets.
  •  No gluing required. Simple removal and replacement.
  •  The CF Gasket accommodates pipe diameters up to 120”/3000mm.
  •  ASTM C361, ASTM C443, ASTM C1619, California Greenbook and CSA A-257 material requirement compliance.

Materials and Identification

Tylox® CF gaskets are manufactured from a variety of synthetic rubber compounds, to meet the material requirements of ASTM C361, ASTM C443, ASTM C1619, California Greenbook, and CSA A257.

The applicable specification(s) and useage mode for a particular gasket are identified by a colored stripe around the periphery of the gasket:

  • Standard
  •  C443, A257, C1619 White Stripe
  •  C361, A257, C1619 Blue Stripe
  •  California Greenbook Green Stripe
  • Oil-Resistant*
  •  C361, C443, A257, C1619 Orange Stripe
  •  California Greenbook Yellow Stripe

* Note that the additional physical properties required to achieve Oil Resistance have a significant impact on availability, handling and cost. Please refer to the pdf file “Oil Resistant Gaskets” in the “Technical” Section of the web-site’s Library.

The above listing covers the standard, North American, specifications. Gaskets materials are available to meet many other specifications. Please consult your Hamilton Kent representative regarding materials to meet your particular specifications.

Pressure Rating

Tylox® Type CF profile gaskets are suitable for use in all systems with up to 13 psig (30 ft Head or 90kPa) pressure requirements.

Pressures up to 22 psig (50 ft Head or 150 kPa) have been obtained with certain joint designs. Please consult your local Hamilton Kent Representative for gasket selection to meet your specific requirements.

MSDS

Tylox® “CF” Gaskets are not WHIMIS listed.

Tylox® “CF” Gaskets are made from cross-linked, polymeric rubber, which is not considered a health hazard. As with any rubber product, the gasket may smolder or burn when exposed to a naked flame. Fire-fighters should wear self-contained, positive-pressure, or pressure-demand, breathing apparatus; and utilize water-spray, air-foam, dry chemical or CO2-type extinguishing media.

Storage and Handling

Proper care of the gaskets prior to installation will ensure maximum ease of installation and maximum sealing properties of the gasket.

All rubber gaskets are required to be stored in a sheltered, cool, dry place at the precasters facility, as well as on the job site.

Gaskets must not be stored near any electrical equipment that produces ozone. They must be protected from prolonged exposure to sunlight, extreme heat in the summer, and extreme cold, snow and ice in the winter.

All gaskets must be protected from harmful substance such as dirt, mud, dust and grit.

All gaskets, other than oil-resistant gaskets, must be protected from contact with solvents and petroleum based greases and oils.
