Karman Rubber KTP tapered plugs cover and seal holes in a variety of applications.

 

Features and Benefits:

  • Tapered to fit various size openings.
  • 4 sizes with through  holes allowing for the insertion of pipettes or tubing.
  • 3 sizes with no through (Solid) holes.
  • Available in 50 Durometer Shore A Neoprene, Natural Rubber, EPDM, and Nitrile (Buna-N).
  • Temperatures ranges from -40º F to 300º F.
  • Other Durometers available upon request.

 

Applications:

  • Water tight applications for plugging or sealing.
  • Mitigates cement displacement in the construction industry.
  • Oil water and gas drilling.
  • Chemical industry.

 

Environmental Data:

 

Natural Rubber (NR)

Advantages:  Outstanding resilience; high tensile strength; superior resistance to tear and abasion; excellent rebound elasticity (snap); good flexibility at low temperatures (-40° F to 155° F).

Limitations:  Poor resistance to heat, ozone, and sunlight; very little resistance to oil gasoline, and hydrocarbon solvents.

  • Operating temperatures should not exceed 155° F.
  • Natural Rubber is not recommended from exposure to oil, gasoline, ozone sunlight.

 

Neoprene (CR)

Advantages:  Good inherent flame resistance; moderate resistance to oil and gasoline; very good resistance to weather, ozone, and natural aging; good resistance to flex cracking; very good resistance to alkalis and acids.

Limitations:  Poor to fair resistance aromatic and oxygenated solvents; limited flexibility at low temperatures (10° F to 180° F).

Nitrile (Buna-N)

Advantages:  Very good resistance to oil and gasoline; superior resistance to petroleum-based hydraulic fluids; wide range of service temperatures (-65° F to 300° F); good resistance to hydrocarbon solvents; very good resistance to alkalis and acids.

Limitations:  Inferior resistance to ozone, sunlight, and natural aging; poor resistance to oxygenated solvents.
