Parker KP78514 Flareless Bite-type Tube Plug M12x1.5

Product Description

The PARKER KP78514 is a flareless bite-type tube plug designed to seal hydraulic and fluid system tubing at M12 x 1.5 metric threaded ports. The bite-type design uses a ferrule or sleeve that bites into the tube wall on installation, creating a leak-resistant mechanical seal without the need for flared tube ends. This plug terminates open tube ends or unused ports in systems where maintaining system pressure and preventing contamination are critical. It is installed by licensed fluid power technicians and hydraulic system mechanics in industrial, mobile, and HVAC-adjacent fluid circuit applications.

The KP78514 is suited for use in hydraulic lines, pneumatic circuits, and fluid distribution systems that use metric M12 x 1.5 threaded fittings. Flareless bite-type plugs of this style are commonly used to cap off test ports, branch ports, or inactive circuit branches during system commissioning, repair, or reconfiguration. This plug ships in a package quantity of three units per pack, making it practical for service technicians who need spares on hand.

Key Features

• Flareless bite-type design eliminates the need for tube flaring prior to installation
• M12 x 1.5 metric thread provides direct fitment to standard metric-threaded ports
• Seals open tube ends and unused ports to prevent contamination and pressure loss
• Packaged in quantities of three for convenient field inventory
• Compact form factor suitable for tight installation spaces

Compatibility

Designed as an OEM-style replacement or service plug for hydraulic and fluid system components using M12 x 1.5 metric flareless bite-type fittings.

Installation Notes

Installation should be performed by a qualified fluid power or hydraulic technician. Depressurize and isolate the system circuit before removing or installing any tube fittings or plugs. Follow the fitting manufacturer torque guidelines for M12 metric bite-type connections and ensure the ferrule seats properly against the tube during assembly. Verify there are no leaks before returning the system to service.
