K69 & K695 Series Material Data:

• The Neoprene elastomer is standard in 30, 40, 50, 60, & 70 Durometer Shore A.
• Operating temperature range (10° F to 180° F).
• Ozone resistant
• Oil, gasoline and solvent resistant.
• Flame resistant
• Structure made of corrosion resistant carbon steel.

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.
