Temperature:

1) NBR: limit temperature -40 ~ 120 ℃, the proposed long-term use temperature -20 ~ 100 ℃

2)FKM: limit temperature -40 ~ 240 ℃, the proposed long-term use temperature -20 ~ 220 ℃

Pressure: up to about 40MPa

Color: 1) Silver White + Black / Brown  2) Yellow + Black / Brown

[Description]: 1) Bonded Washer for the spiral pipe fittings and plug sealing,
it is generally used with the card-type pipe joints, used to block the mouth, mainly for hydraulic pipe thread joints threaded end Sealed.
Applicable to the United Kingdom, the United States standard British thread and France, Germany, the standard metric threaded connection of the end of the static seal.

2) Bonded Washer suitable for oil-based piping systems, common welding, card sets, expansion fittings, plugs and mechanical pressure system seals, to prevent oil, fuel, water and pharmaceutical leakage.

3) Because the Bonded Washer structure is simple, sealed and efficient, and low prices, so that it is widely used in the machinery manufacturing industry.


3、Sectional drawing

Inside diameter * Outer diameter * Thickness is the commonly used expression method of Bonded Washer .
As the default, it can be expressed according to the thread size d1 * p, such as M10 * 1, G1 / 8A and so on. Size can be ordered on demand
Warm tips:
M = metric common thread, G = cylindrical pipe thread, A = class A precision d1 = nominal diameter of thread P = pitch
O = Outer diameter ID = inner diameter H = thickness
