Parker P00098 Steel Flared Tube Cap 3/16 in 37 Degree

Product Description

The PARKER P00098 is a steel flared tube cap designed to seal 3/16 inch OD tubing with a 37-degree flare connection. It provides a pressure-tight end closure on hydraulic, refrigeration, and fluid-power lines when a port or line must be capped off during service, testing, or system assembly. The cap is rated for a maximum working pressure of 7500 psi and a maximum working temperature of 500 degrees F, making it suitable for high-pressure hydraulic circuits and demanding fluid systems. Licensed plumbers, HVAC technicians, and hydraulic system technicians install this fitting as part of routine maintenance and system commissioning procedures.

This cap is suited for use on tubing systems in residential and commercial HVAC, hydraulic power units, and fluid-power assemblies where 37-degree flare connections are specified. The 37-degree flare standard is common in hydraulic and refrigeration circuits requiring robust, leak-resistant fittings. It is also used in industrial and mobile hydraulic applications where a positive seal on an unused port is required. The P00098 ships in a package quantity of 5 units, making it practical for stocking in a service vehicle or parts inventory.

Installation Notes

This fitting is installed by licensed HVAC technicians, plumbers, or hydraulic system technicians. Depressurize and isolate the system completely before removing or installing any tube fitting. Thread the cap onto the flare fitting by hand first to confirm engagement, then tighten with a wrench to the torque appropriate for the system per the applicable SAE or ISO standard. Do not overtighten, as steel flare fittings can deform the sealing surface if excessive force is applied.
