Foreword

This standard is one bite type pipe fittings series.

8434-1 this standard pipe joint structure type and size ISO.2007 "first metal pipe fittings for fluid power and general use Part 1. 24 ° compression fittings "(in English) of the relevant part of the basic agreement.

This standard is GB/T 3756.1-1983 "card sets butt straight couplings" and GB/T 3756.2-1983 "card sets straight butt Revision way Connection "in. The main amendments are as follows.

--- The contents of the two standards were revised to integrate, cancel the type and size of the original standard, provides sealing cone sleeve type group Closing straight couplings type and size;

--- Modify the Chinese and English names.

The use of standard GB/T 3756-2008 standard number, intended to reflect the bite type pipe joint standard series, but this standard access Head type and original standard connector types are not interchangeable.

Since the implementation of this standard replaces GB/T 3756.1-1983 and GB/T 3756.2-1983. The standard proposed by China Machinery Industry Federation.
