Introduction
This manual provides the necessary information on how the DT and HD family of connectors (shown in Illustration 1) are properly serviced.Do not perform any procedure, outlined in this manual, or order any parts until you read and understand the information contained within.Deutsch HD and DT style connectors are very similar. Differing only in shape and color, the function and servicing techniques are the same. Both consist of a plug and receptacle.
Illustration 1. Typical DT (1) And HD(2) Style Connectors.Gray colored DT style connectors were changed in mid-1999 to improve the replaceable seal between the plug and receptacle. For easy recognition, the most current DT style connector plugs and receptacles found in this kit will be colored black. The current green wedge design will also be easily identified from the former orange color.The plug half of the DT style connector has a seal at the mating end. This seal has been improved on black connectors to help prevent slipping and is replaceable. This improvement will help keep moisture and dirt from entering the connector. The current seal design (2, Illustration 2) is not interchangeable with the former design (1, Illustration 2). The receptacle has also changed to the new colors.
Illustration 2. Seal Designs. (1) Former Seal On Gray Plug. (2) Current Seal On Black Plug. The seals, shown in Illustration 2, are NOT interchangeable.The Pin and Socket terminal crimping procedure (shown on page 8) is identical for both HD and DT style connectors.Receptacles accept pin terminals. Wedges, assembled at the mating interface, lock the terminals into position. The original orange wedges are now green and fit into the current black connectors. Plugs accept sockets. Wedges lock the sockets into position. Green and orange receptacle wedges are interchangeable (refer to the "DT Style Connector Compatibility" section in this manual for additional information). DT style connectors are joined by aligning the latching mechanisms and pushing the connectors together.
Illustration 3. Typical HD Style Connector.HD style connectors are easily recognizable, by the round connector bodies. HD style connectors are sealed with rubber gaskets, which are not replaceable. Wedges are not required with this design. The connectors are joined using a quarter-turn locking ring.Serviceable Parts

The 175-3700 DT Style Field Service Group and the 190-8900 HD Style Deutsch Connector Group do not contain the 1U-5804 Crimp Tool. The 1U-5804 Crimp Tool should be ordered separately.DT Style Connector Compatibility
The original gray colored DT style Deutsch connectors with orange wedges have been redesigned to improve the plug and receptacle body sealing. The redesigned connectors are black with green wedges.Interchangeability between plug, receptacle, and wedges is possible in some cases. The seals for the black and gray plugs are NOT interchangeable.Use the
