Dichtomatik N70212 O-Ring, 212 Dash Number, 0.859 in ID x 1.137 in OD, Nitrile Rubber, 70 Shore A Durometer, Import, Custom 212
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

Dichtomatik 75115253 O-Ring, 243 Dash Number, 4.109 in ID x 4.387 in OD, PTFE, 55 Durometer, Import, Custom 243-TEFLON
O-rings are endless, ring shaped sealing elements with a circular cross-section that are manufactured from elastomer materials or PTFE. The designation of an O-ring is derived from the dimensions of its inner diameter and cord width in millimeters, along with the name of the material and its Shore A hardness.
Browning® 1073519 QD Bushing, 2-7/8 in Dia Bore, 3-13/16 in Dia Barrel, 6 in Dia Flange, 2.64 in OAL, Ductile Iron
Sure-Grip® quick detachable bushings are easy to install and remove. Split-through flange and taper provide a true clamp on the shaft that is equivalent to a shrink fit. All sizes except JA and QT have a set screw over the key to help maintain the bushing's position on the shaft until the cap screws are securely tightened. Versatile Sure-Grip® bushings permit the mounting of the same mating part on shafts of different diameters and the mounting of different sheaves on the same shaft using the same bushing.
