(1) Dimensions in Millimeters.
(2) CAUTIONARY NOTE REGARDING HEX BUSHING.
Hex head bushing if one-size reduction should not be used in services where they might be
subject to harmful loads and forces other than internal pressure.
螺纹要求（这对您很重要）
1、以上均为锻钢高压实心堵头，额定压力可大410KG压力。
2、我们常规备货的螺纹有NPT（美制）60度锥管螺纹，PT（英制）55度锥管螺纹，其中RC/ZG/R，英制在国内非常常用，又称水管牙，美制非常少见，订货时请务必确认，两者不能通用。
3、我们工厂不接201、301等低质不锈钢材料的订单，最低为304材质起做。
4、如果您需要G螺纹，需定做，部分G外螺纹可以用PT（英制螺纹代替），外螺纹PT可以连接G内螺纹，反过来就不能用。
5、管件几何尺寸制造依据ASME B16.11及GB/T14383，螺纹制造标准为BSPT（ISO7/1），NPT（ASME B1.20.1）
