Parker 12 Vbu-s Bite-type Tube Male Elbow 3/4 in Nptf

Product Description

The PARKER 12 VBU-S is a flareless bite-type tube male elbow fitting designed to connect tubing to a male NPTF-threaded port in a 90-degree configuration. It accepts 3/4-inch outside diameter tubing and threads into a 3/4-inch NPTF port, creating a secure, leak-resistant mechanical connection without requiring a flared tube end. The bite-type design uses a ferrule that bites into the tube wall on tightening, providing a reliable grip and seal. This fitting is used in hydraulic, pneumatic, and fluid-transfer lines and is typically installed by pipefitters, hydraulic technicians, or plumbing mechanics working on industrial or commercial fluid systems.

This fitting is suited for use in flareless tube assemblies where a directional change from tube to threaded port is needed. Common applications include hydraulic control lines, compressed air distribution, and fluid-power systems in industrial and commercial settings. The NPTF thread form provides a dry-seal connection, reducing reliance on thread sealant for pressure integrity. The 3/4-inch tube OD and 3/4-inch NPTF thread size make this a standard size for mid-range fluid-line assemblies.

Key Features

• Flareless bite-type design eliminates the need for tube flaring during assembly
• 3/4-inch NPTF male thread provides a dry-seal tapered connection
• Accepts 3/4-inch OD tubing for a secure ferrule-driven grip
• 90-degree male elbow configuration allows directional routing in tight spaces
• Compatible with hydraulic, pneumatic, and general fluid-transfer applications

Compatibility

Designed as an OEM-style flareless bite-type fitting for use with 3/4-inch OD tubing and 3/4-inch NPTF-threaded ports in hydraulic, pneumatic, and fluid-power systems.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician familiar with flareless bite-type fitting assembly procedures. De-pressurize and isolate the fluid line completely before disassembly or installation. Pre-set the ferrule on the tube according to the fitting manufacturer's assembly procedure before final tightening into the port. NPTF threads are designed as dry-seal connections, but consult system specifications before applying thread sealant.
