Taiwan Wall top factory direct supply of imported oil resistant nitrile rubber O-ring in nbrO-ring, fluorine rubber O-ring, EPDM EPDM rubber O-ring seal these three materials. Sealing principle import O-ring: O type ring in the groove to be dark, because of the depth of the groove is smaller than the o-ring seal, so the O-ring is compressed (O-ring thickness less than the depth of the trench). This compression becomes O-ring compression margin. Import O-ring nbr rubber material characteristics: volume fraction of the installation, a small footprint. Simple structure, easy installation and o-ring cannibalize. Various types of materials available in wider temperature range (-60 ℃ - + 220 ℃) ??to use on site. Under way in times of stress, o-ring can also play a sealing function. Compared with other ring, affordable. Rich import nbrO-ring stock, can cope with short lead times. Imported oil O-ring - our outstanding advantages 1. Appearance: fine workmanship, through a special mill treatment, no parting line, no glitches; 2. Material: we select all imported glue material, product performance, quality is absolutely trustworthy ; 3. Prices: Our products are imported products in the lowest price; 4. cash reserves, general import nitrile nbro-rings, imported fluorine rubber O-rings, imported silicone o-rings, imported EPDM O-type ring, imported chloroprene rubber O-rings and other materials are available from stock; American standard AS-568 O-ring rubber O-ring --- imported American Standard (AS-568 O-ing Sizes) model diameter × diameter O ring model diameter × diameter O-ring type O-ring inner diameter × diameter O-ring type O-ring inner diameter × diameter O-ring AS568-001O ring 0.74 × 1.02 AS568-102 1.24 × 2.62 AS568-157 113.97 × 2.62 AS568-233 72.62 × 3.53 AS568-002 1.07 × 1.27 AS568-103 2.06 × 2.62 AS568-158 120.32 × 2.62 AS568-234 75.79 × 3.53 AS568-003 1.42 × 1.52 AS568-104 2.84 × 2.62 AS568-159 126.67 × 2.62 AS568-235 78.97 × 3.53 AS568-004 1.78 × 1.78 AS568-105 3.63 × 2.62 AS568-160 133.02 × 2.62 AS568-236 82.14 × 3.53O ring AS568-005 2.57 × 1.78 AS568-106 4.42 × 2.62 AS568-161 139.37 × 2.62 AS568-237 85.32 × 3.53O ring AS568-006 2.90 × 1.78 AS568-107 5.23 × 2.62 AS568-162 145.72 × 2.62 AS568-238 85.32 × 3.53O-ring seal top Wall Technology Co., Ltd. Taiwan supply of imported oil O nbr-ring groove design: in the case of sports use, the use of margin compression O-ring seal when have sliding resistance, compression set have a huge impact, and therefore must be controlled if necessary minimal inside. When used at sports, especially speed, poor lubrication conditions of the case, set the margin compression set is much smaller than the average movement with O-ring. Necessity choose to import oil nbr rubber O-ring material: O type ring rubber essential characteristic means good flexibility, good compression set resistance, good abrasion resistance, excellent heat resistance and liquid and gas will not be used for intrusion-resistant, longer service life and so on. However, because these materials are in line with all the features No, it is in accordance with a variety of uses, it is necessary to choose according to their use of different materials for use.
