British system (In terms of use occasions, the British system is generally used;) a calculation method based on the British system, including length, area, weight, etc. WONEPART seals tell you the specifications and dimensions of the friction length and projected area of some British standard O-rings and inch seal.
Note: English unit and length calculation method:
1mile=1.609344km=1760yards=5280feet
1yard=0.9144m=3feet
1fath=2yards=1.8288m
1furlong=220yards=201.17m
1foot=30.48cm=12inches
1inch=2.54cm
1 inch = 1000 mils (mil, thou)
Note: The unit of area in English system and the calculation method of area:
Most area units are formed by squaring the length unit, as long as the base number is squared.
1acre=4840 sq yards (square yard)=1/640 sq mile (square mile)
The names of most British Imperial Units and United States customary units are often the same, but the specific definitions are different, and some are even quite different. This is because after the independence of the United States, its measurement system was separated from the United Kingdom, and the American imperial units used were different from the British imperial units. In the United Kingdom, imperial units were standardized in 1824.
Two speed units of mile/hour (mph) and kilometer/hour (km/h) will appear on the dashboard of American American vehicles. When driving across borders, the British system is adopted in the United States and the metric system is adopted in Canada/Mexico. ; In addition, in the American professional baseball, the pitching speed of the pitchers is in imperial units, while the pitching speed of the international baseball team/Japan professional baseball/Korea professional baseball/Chinese professional baseball pitchers is in metric units. In Hong Kong, China, the imperial system is still widely used in some units, such as "pound" and "ounce"for weight; "feet" and "inch" for length; "yard" is still often used for cloth/ Paper and electrical wires are bought and sold; “square feet” are used to calculate the area of buildings; “gallons” of volume are used for the water consumption of the Water Supplies Department’s water bill. Influenced by American imports of cooking utensils and foods (such as dairy products), quarts are also used. Other units have been rarely used.
There are also a few other countries that still officially adopt imperial units, such as Liberia and Myanmar. In Malaysia, several units are still widely used: "square feet" are still used for house and land transactions, "inches" are still units used to measure waist circumference in daily life, building materials are traded by "inches", middle-aged people “Square” is often used to express height, and the larger land area is mostly expressed with “acre” (a transliteration of “acre”). "Gallons" are occasionally seen in newspaper reports about water storage in dams. Other units have been rarely used.

CS: Cross section
ID: inner diameter
In the United States, the most common industry standard for o-rings is AS568, which means "AS568-" plus the number
For example: AS568-028
Standard American standard size: CS 0.070 x ID 1.364
Metric size: CS 1.78 x ID 34.65
Nominal score size: CS 1/16 x ID 13/8
The global o-ring and seal ring size reference chart covers the AS568 o-ring size issued by the Society of Automotive Engineers (S.A.E), and includes the extended size of the 400 series. The purpose of this chart is to develop the diameter, cross section, tolerance, and dimensional identification codes of O-rings and straight threaded pipe joint boss washers used in sealing applications.
The main purpose of o-ring, sealing ring, guide ring and back support ring:
1. Dynamic and application environments requiring lubricants
2. Exposure to harsh chemical environment
3. Electronics, wireless communication, microwave, cable insulation
4. Application environment of guide ring and back support ring
5. General industrial use
Not only inch O-rings, but also various inch piston seal, rod seal, hydraulic seal for construction machinery, construction machinery seal repair kit brands: Can be applied to Caterpillar Carter, Komatsu, John Deere, Hitachi, Kobelco, New Holland, Liebherr, JCB, CASE, VOLVO, Doosan, Hyundai, SANY, XCMG, ZOOMLION, LIUGONG and so on. Among them, there are 26000 kinds of Caterpillar seal and seal kits products, 15000 kinds of Komatsu seals, and 10000 kinds of Hitachi seals. Parts, all use the original part numbers.
Wonepart cooperates with many express companies, UPS, FEDEX and DHL can reach all countries in the world in almost three days. Extensively cooperate with China's Komatsu, Hitachi, Carter and other machinery agents to ship more than 10,000 sealed containers per airline.
