Dichtomatik N70014 O-Ring, 014 Dash Number, 0.489 in ID x 0.629 in OD, Nitrile Rubber, 70 Shore A Durometer, Import
O-rings are closed circular rings of circular cross-section. They are made through vulcanization from form tools as a complete ring. The sealing function of the O-ring is achieved by the deformation of the cross-section when installed and compressed in its housing. The O-ring can be compressed either radially or axially in its installation housing. In operating conditions the pressure exerted by the media reinforces the sealing function, as under pressure the elastomer material functions as a non-compressible fluid.

- Good chemical resistance to mineral oils and greases
- The physical and chemical resistance properties of NBR materials are determined by the acrylonitrile (ACN) content of the base polymer which can vary between 18 and 50%
- Low ACN content ensures good flexibility at low temperatures, but offers limited resistance to oils and fuels
- As the ACN content increases, the low temperature flexibility reduces and the resistance to oils and fuels improves
- Physical and chemical resistance properties of NBR materials are also affected by the cure system of the polymer
- Peroxide cured materials have improved physical properties, chemical resistance and thermal properties as compared to sulfur-donor-cured materials
- Standard grades of NBR are typically resistant to mineral oil-based lubricants and greases, many grades of hydraulic fluids, aliphatic hydrocarbons, silicone oils and greases and water to about 80 deg C
- NBR is generally not resistant to aromatic and chlorinated hydrocarbons, fuels with a high aromatic content, polar solvents, glycol based brake fluids and non-flammable hydraulic fluids (HFD)
- NBR also has low resistance to ozone, weathering and aging, but in many applications this has no negative effect

DuMONT Minute Man® replacement shims for use with Keyway Broaches are available for spares and to replace lost or damaged shims. The smallest Broaches cut in one pass and require no shim. Multiple pass Keyway Broaches are furnished with all necessary shims unless otherwise noted. Progressive shims may be purchased for use with our largest Keyway Broaches. A shim is required to compensate for the thickness removed following a Keyway Broach's cutting pass. The addition of a shim serves to move the Broach forward towards its standard finished cutting depth. Subsequent passes require the stacking of shims. Replacement or extra shims are provided in shim sets corresponding to the Broach size and letter designation in the quantity necessary to cut to standard depth. Please specify EDP number when ordering replacement or extra shims.
