Parker 3 Vbu-s Bite-type Male Elbow 3/16 in 1/8 Nptf

Product Description

The PARKER 3 VBU-S is a flareless bite-type tube male elbow fitting designed for secure, leak-resistant connections in hydraulic and instrumentation tubing systems. It accepts 3/16-inch tube OD and threads into a 1/8-inch NPTF port. The bite-type design uses a ferrule that bites into the tube wall when tightened, eliminating the need to flare the tube end before assembly. This fitting is installed by plumbers, pipefitters, and fluid-system technicians working on pneumatic lines, hydraulic circuits, and process instrumentation runs where a 90-degree direction change is required.

This fitting is suited for residential and light commercial fluid or pneumatic systems where tube lines must transition at a right angle into an NPTF-threaded port. Typical install scenarios include compressed air distribution, hydraulic control lines, and instrumentation tubing panels. The 1/8-inch NPTF thread provides a dry-seal connection that does not rely solely on a sealant compound to prevent thread leakage.

Key Features

• Flareless bite-type design — no tube flaring required before assembly
• 3/16-inch tube OD connection for small-bore tubing runs
• 1/8-inch NPTF dry-seal male thread for leak-resistant port entry
• 90-degree male elbow configuration for compact direction changes
• Compact, lightweight construction at 0.01 pounds

Compatibility

Designed as an OEM-style replacement or service fitting for flareless bite-type tube systems using 3/16-inch OD tubing and 1/8-inch NPTF threaded ports.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or hydraulic system technicians. Depressurize and isolate the fluid or pneumatic line completely before disconnecting any fittings. NPTF threads are designed for dry-seal engagement; follow the fitting manufacturer torque guidance and applicable system codes when making up threaded connections. Ensure the tube is cut square and deburred before inserting into the bite-type ferrule to achieve a proper bite and seal.
