- One of the key features of E3 spark plugs is their unique DiamondFire electrode design. This design allows for better ignition of the air-fuel mixture in the engine, resulting in more efficient combustion and improved power output. The DiamondFire electrode also reduces carbon buildup and fouling, leading to cleaner engine operation and longer plug life.
The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth, or use our brochure to establish the M Barnwell Services ordering reference. Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.
④ Dimensional numbers Shaft number 45: The seal suits the shaft diameter of ϕ45 mm. Housing bore number 70: The seal suits the housing bore diameter of ϕ70 mm. Width number 8: The seal width is 8 mm. ⑤ Special shape code
Imperfections on the shaft
1. Oil seals have three basic components: sealing element, metal case, and spring.
Material Code ISO 1629
Of course, all rubber materials and seals will provide a range of benefits; however, you will need to consider chemical compatibility, sufficient temperature ranges, pressure ranges, and more.
The sealing lip of the RST-D is more heavy-duty, so it can cope with pressures of up to 10 bar at slightly lower rotation speeds.
Select your oil seal type according to Table 2.
