Parker PT-00231 Bite-type Tube 90 Elbow 1 in Nptf

Product Description

The PARKER PT-00231 is a flareless bite-type tube 90 degree elbow fitting designed for use in hydraulic and fluid conveyance systems. This elbow accepts a 1 inch tube OD and connects to a 1 inch NPTF threaded port. The bite-type design uses a ferrule that deforms and grips the tube wall on assembly, eliminating the need for tube flaring. Licensed plumbers, pipefitters, and hydraulic technicians install this type of fitting in fluid power lines, pneumatic systems, and process piping where a secure, leak-resistant 90 degree directional change is required. The NPTF thread form provides a dry-seal connection that resists leakage under pressure without relying solely on sealant tape.

This fitting is suited for applications requiring a compact 90 degree turn in tubing runs within industrial, commercial, and trade service environments. Common installations include hydraulic power units, compressed air distribution systems, and process fluid lines where tube routing must change direction at a port face. The flareless bite-type system makes it practical for field assembly where flaring tools are not available or where space constraints limit tube end preparation.

Key Features

• Flareless bite-type design eliminates tube flaring — ferrule grips tube OD on tightening
• 90 degree elbow configuration for directional changes at threaded ports
• 1 inch NPTF dry-seal thread for leak-resistant port connections
• Accepts 1 inch tube OD
• Package quantity of 2 per unit sold

Compatibility

Designed as an OEM-style flareless bite-type elbow fitting for fluid power and process piping systems using 1 inch OD tubing with 1 inch NPTF threaded ports.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or hydraulic technician following applicable system codes and manufacturer torque guidelines. Depressurize and isolate the fluid system completely before removing or installing any fittings. On initial assembly, advance the nut to the recommended preset position to seat the ferrule, then tighten the specified additional turns per bite-type fitting procedure — do not over-tighten, as ferrule damage will result in a failed seal. Inspect the tube end for squareness and freedom from burrs before inserting into the fitting body.
