The AKM 72 Pcs JIC 37° Flare Cap and Plug Kit is identified as a hydraulic hose, tube, and pipe fitting set. Cap-and-plug kits are generally used to close open connection points during service, storage, maintenance, or repair work. The correct fitting standard, thread form, size, and sealing method should always be confirmed before installation.
Quick Overview
This kit is intended for readers looking for an AKM-branded set of JIC 37° flare caps and plugs in several dash sizes. Because hydraulic fittings must match the connection being sealed, the most important details to confirm are the fitting standard, size, thread compatibility, and whether a separate seal is required for the intended application.

| Dash Sizes Identified | -04, -06, -08, -10, -12, and -16 |
What the Kit Is Designed For
Hydraulic caps and plugs are used to close exposed ports, hose ends, tubes, and pipe connections. A cap typically closes one style of connection, while a plug closes another. Using the appropriate piece can help keep an open hydraulic circuit protected while equipment is being assembled, transported, serviced, or stored.
JIC 37° flare fittings use a specific connection design. They should not be treated as interchangeable with NPT, ORFS, metric, or other hydraulic fitting standards. A matching dash size alone does not establish compatibility, so the fitting style and the mating component should be checked together.
Size Range and Identification
The set is identified with dash sizes -04, -06, -08, -10, -12, and -16. Dash numbers are commonly used to identify hydraulic hose and fitting sizes, but the number does not by itself confirm every thread or connection detail. The equipment documentation, existing fitting, or a suitable measuring method should be used to verify the required size.
- Compare the new cap or plug with the connection it will seal.
- Confirm that the connection uses the JIC 37° flare standard.
- Match the dash size to the hose or fitting manufacturer’s specifications.
- Check whether the application requires a seal, O-ring, or another sealing component.
Materials and Construction Details to Confirm
Material, surface finish, thread dimensions, and pressure suitability are important considerations for hydraulic fittings. These details can affect resistance to corrosion, service life, and suitability for a particular fluid-power system. The exact material and finish for the requested set should be confirmed in the product documentation before use, especially where the fittings will be exposed to moisture, chemicals, high temperatures, or high pressure.
Precision threading is also important because damaged, incorrect, or poorly matched threads can prevent proper engagement. A cap or plug should fit smoothly by hand for initial engagement. Forcing a component into a connection can damage the threads or the mating fitting.
Common Applications
Cap and plug sets are commonly kept as service accessories for hydraulic maintenance. They may be useful when a hose is removed, a port is temporarily unused, or an assembly needs protection from dirt and debris. They can also help organize repair work when several hydraulic connection sizes are used on the same equipment.
Potential work settings include agricultural machinery, construction equipment, industrial fluid-power systems, vehicles, and general hydraulic servicing. Suitability depends on the exact fitting specification, system pressure, fluid, temperature, and installation requirements. The set should not be used in a critical application without confirming those conditions.
Storage and Organization
A multi-size kit is most useful when each piece can be identified quickly. Keeping the caps and plugs separated by dash size can reduce the chance of selecting an incorrect fitting during maintenance. Clean storage also helps limit contamination of sealing surfaces and threads.
Before placing a fitting into storage, inspect it for damaged threads, dents, corrosion, or debris. Any component that does not appear serviceable should be set aside for further inspection rather than mixed with usable parts.
Things to Consider Before Use
- Connection standard: Verify that the equipment uses JIC 37° flare connections rather than another fitting standard.
- Dash size: Match the selected cap or plug to the documented size of the hose, tube, or port.
- Sealing method: Determine whether the connection seals at the flare, thread, O-ring, or another interface.
- System conditions: Confirm pressure, temperature, and fluid requirements before placing a fitting into service.
- Condition of mating parts: Inspect the connection for damaged threads, contamination, or worn sealing surfaces.
- Temporary versus permanent use: A cap or plug used during servicing may not be suitable as a permanent system closure unless the manufacturer’s specifications support that use.
Frequently Asked Questions
What does a hydraulic cap and plug kit do?
It provides components for closing compatible hydraulic connection points. Caps and plugs can help protect open hose ends, tubes, pipes, and ports during maintenance or storage.
Are JIC 37° flare fittings interchangeable with NPT fittings?
No. JIC 37° flare and NPT are different connection standards. Their sealing methods and thread designs differ, so they should not be substituted for one another without an appropriate, specified adapter.
How should the correct dash size be selected?
Use the equipment documentation or identify the existing fitting and hose specification. The dash size should be matched along with the connection standard and thread details.
Does a cap or plug always need an additional seal?
Not necessarily. The required sealing method depends on the fitting design. Some connections seal at a flare or another mating surface, while others may require a specified seal or O-ring. Check the relevant fitting documentation.
Can the fittings be used in any hydraulic system?
No. Compatibility depends on the connection type, size, system pressure, fluid, temperature, and installation requirements. Confirm all of these details before use.

Final Thoughts
The AKM 72 Pcs JIC 37° Flare Cap and Plug Kit is presented as a multi-size hydraulic fitting set for compatible JIC connections. Its usefulness depends on accurate matching of the fitting standard, dash size, thread details, sealing method, and system conditions. Confirming those specifications before installation is the most important step for safe and appropriate use.
