Parker PT-00375 Flareless Bite-type Tube Cap 0.5 in Steel

Product Description

The PARKER PT-00375 is a flareless bite-type tube cap designed to terminate or seal hydraulic and fluid-power tube lines without the need for a flared fitting end. Machined from steel and rated to 5000 psi maximum working pressure, this cap threads onto a 3/4-16 UN/UNF male fitting to close off a 0.5-inch OD tube assembly. The 24-degree flare angle and bite-type design create a reliable metal-to-metal seal suitable for high-pressure line work. With an overall length of 0.87 inches and a hex size of 0.88 inches, the cap fits standard wrenching tools used in hydraulic and fluid-power service environments. Installed by hydraulic technicians, millwrights, and fluid-power specialists.

This tube cap is used in hydraulic, pneumatic, and industrial fluid-power systems where open tube ends must be capped during service, testing, or storage. It is appropriate for residential and commercial equipment applications requiring a 0.5-inch OD flareless tube termination point. The bite-type design seats against the tube ferrule or sleeve, making it suitable for high-pressure plumbing runs in mobile and stationary hydraulic systems. Sold in packages of 5 units, making it convenient to keep on hand for service calls and bench work.

Installation Notes

Installation and removal should be performed by a qualified hydraulic or fluid-power technician. Depressurize and de-energize the system fully before removing or installing any tube fitting or cap. Thread engagement should be confirmed by hand before applying wrench torque to avoid cross-threading. Follow applicable industry standards and equipment manufacturer guidelines for hydraulic line service and reassembly.
