Midland Industries SS304-C-02 Stainless Steel Jic Cap

Product Description

The MIDLAND INDUSTRIES SS304-C-02 is a single-piece cap fitting designed to seal a 1/8-inch female JIC port. Machined from 304 stainless steel, it delivers a maximum operating pressure of 5000 psi and an operating temperature rating of 1000 degrees F. The cap uses a 5/16-24 thread engagement and measures 0.5 inches in length. It is used to dead-end or protect an open JIC port during service, storage, or system reconfiguration. Plumbers, pipefitters, and hydraulic system technicians install this fitting wherever a JIC line end needs to be capped cleanly without a secondary seal component.

This cap fits directly into any 1/8-inch female JIC port and is suited for hydraulic lines, fuel systems, instrumentation tubing, and high-temperature fluid circuits. The stainless steel construction makes it appropriate for corrosive-fluid environments, high-pressure hydraulic circuits, and installations where carbon steel fittings would be unsuitable. It belongs to the Midland Industries SS0304-C series of JIC caps, which are cataloged under SS JIC Adapters within the stainless steel adapter product line.

Key Features

• Single-piece cap construction with no secondary components required
• 5000 psi maximum operating pressure for high-pressure hydraulic and fluid system use
• 1000 degrees F operating temperature rating for extreme-heat applications
• 304 stainless steel construction resists corrosion in harsh fluid environments
• 1/8-inch female JIC connection with 5/16-24 thread
• Compact 0.5-inch length minimizes protrusion at capped ports

Compatibility

Designed as a direct-fit cap for 1/8-inch female JIC ports in hydraulic, fuel, and instrumentation systems requiring 304 stainless steel fittings rated for high pressure and elevated temperature service.

Installation Notes

Installation is performed by qualified pipefitters or hydraulic technicians. Depressurize and isolate the system completely before installing or removing any JIC cap. Thread the cap by hand first to confirm thread engagement before applying a wrench to avoid cross-threading. Follow applicable system codes and manufacturer torque guidance for JIC fittings of this thread size.
