Description:
Hydraulic plugs are fittings that protect the open end of the hydraulic hose from damage, such as during the transportation.
4J plug fittings are known for their 37-degree flare on the seating surface. They are attached to the hydraulic hose fitting to form a strong seal to keep out dust and dirt and to prevent damage to the threads.
If you want free samples or want to know more information about JIC plug fitting, please contact us.
Features and Benefits:
Male JIC Connection
External straight threads and a 37° flare seat for a matching female JIC connection.
Hex Body
Hex flats provide wrench access during installation and removal.
Multiple Size Options
Select individual part numbers from the dimension table for your required thread sizes.
Defined Sealing Interface
The matching cone surfaces provide the seal; thread size and seat geometry must both be checked.

Match the thread diameter and pitch to the female connection, then confirm that the mating seat is JIC 37°. A matching thread alone does not establish a compatible connection.
Use the drawing to check overall length, thread length, and wrench clearance. Dimensions should be read with the units shown in the table. Working pressure must be confirmed for the selected size, material, and operating conditions.

Take a closer look at the 4J JIC male plug, including its external thread, 37° cone seat, and hex body. Use the product views alongside the dimension table to compare the connection details and available wrench clearance.
When matching an existing component, check both the thread specification and the sealing seat. Similar thread sizes can appear on different hydraulic connections, so a visual comparison should be supported by dimensions or a reference drawing.
Send Topa your part numbers, quantities, and material requirements. Include a drawing or clear photos of the mating connection if you need help reviewing the specification.
