注：
1． 本体材料：黄铜，碳钢，304不锈钢，316不锈钢。
2． 密封材料及温度范围：丁腈橡胶（黄铜，碳钢及304不锈钢的标准密封材料）：-40 ℃ 至 +120 ℃。
3． 真空度: 696毫米汞柱（93kpa) 。 快换在连接和断开时均可用于真空环境（除1-1/2" 和2-112"外。这两个尺寸的快换接头不推荐在断开状 态下用于真空环境)。
4． 额定压力类型：
低循环，无脉冲额定压力：应用于较低循环且无周期性脉冲应用环境时适用的压力等级。典型应用包括液压工具，矿用液压支架及高压流体输送（如抽取油井中的水或泥浆）等。
ANSI/SO 额定压力：应用于有正常至中等液压冲击环境时适用的压力等级。典型应用包括通用工业设备，冲压机
，农用机械等。脉冲测试在125% ~ 133%倍额定压力下进行。
Caution:
1. body material: brass, high-carbon
steel, 304-grade stainless steel, 316-grade stainless steel.
2. Sealing material and temperature range: Nitrile - butadiene rubber ( NBR ) (brass 、and standard sealing material
of 304 stainless steel): -4 ℃ to +12 ℃ Fluoroelastomer (standard sealing material of 316 stainless
steel): -25 ℃ to +200 ℃
3. Vacuum Level: 696 mmHg (93 kPa).
Quick couplings can be used in vacuum environments when connecting and
disconnecting (except for 1-1/2" and 2-1/2" sizes, which are not recommended
for use in vacuum environments when disconnected).
4. Rated Pressure Types:
Low Cycle,
Non-Pulsating Rated Pressure: Applicable pressure rating for environments
with low cycles and no periodic pulsations. Typical applications include
hydraulic tools, hydraulic supports for mining, and high-pressure fluid
transport (such as extracting water or slurry from oil wells), etc.
ANSI SO Rated Pressure: Applicable pressure
rating for environments with normal to moderate hydraulic shock. Typical
applications include general industrial equipment, stamping machines,
agricultural machinery, etc. Pulse tests are conducted at 125% and 133% of
the rated pressure.
