Parker PT-00899 Bite-type Tube Reducing Adapter 1/2x3/8 Bspp

Product Description

The PARKER PT-00899 is a flareless bite-type tube reducing adapter designed for high-pressure hydraulic and fluid power tubing systems. It transitions between two tube sizes using a BSPP (British Standard Parallel Pipe) thread connection, eliminating the need for flared tube ends. Constructed from steel, this adapter handles a maximum working pressure of 400 bar and measures 37 mm overall length. It is installed by hydraulic technicians and pipefitters working on industrial fluid systems where reliable, leak-resistant fittings are required at reduced tube diameter transitions.

This reducing adapter is suited for industrial hydraulic lines, fluid power circuits, and high-pressure tubing assemblies that require a step-down connection from a 1/2-inch BSPP port to a 3/8-inch BSPP port. The bite-type flareless design grips the tube mechanically without requiring tube flaring, making it practical for field assembly and retrofit installations. It is commonly used in industrial machinery, mobile equipment hydraulics, and process piping where BSPP thread standards are specified.

Key Features

• Flareless bite-type design eliminates tube flaring for faster field assembly
• Rated to 400 bar maximum working pressure for demanding hydraulic applications
• BSPP thread type ensures compatibility with British Standard Parallel Pipe fittings
• Steel construction provides strength and durability under high-pressure cycling
• Reducing adapter profile steps down from 1/2-inch to 3/8-inch thread sizes in a single fitting
• 27 mm hex size accommodates standard open-end or combination wrenches

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems specifying BSPP flareless bite-type reducing adapters in 1/2 x 3/8 thread sizes.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Use a properly sized wrench on the 27 mm hex to achieve a secure connection without over-tightening. Verify BSPP thread engagement and inspect for leaks before returning the system to service.
