1、微型高压软管两端可任意选定接头的连接形式。
2、用户欲订购一端是快换式接头，其接头螺纹为M16，另一端是直接接压力表，其接口螺纹为M14×1.5,通径为3mm,软管长度为1.5m的软管总成，订货型号是：HFH2-P1-3-P-1.5。
3、订购直接接压力表形式的软管总成时，若用户需要带压力表，则要在订单上说明压力表的量程及表径等。
ORDERING EXAMPLE
1、Any connecting type can be select for ends of the hose.
2、For example,One end is quick fitting of connecting thread is M16,The other is direct to connect with pressure gauge of thread is M14×1.5,Now Dia 3mm,the length ofhose assembly is 1.5M,The model of this is:HFH2-P1-3-P-1.5.
3、If you order the hose assembly is direct to connect with pressure gauge,ａnd you aiso need the pressure gauge,the pressure range and gauge dismeter should be expressed in text. |
