Parker 68VL-3-2 Compression Tube Connector Brass 600 Psi

Product Description

The PARKER 68VL-3-2 is a brass compression tube connector designed to join 3/16-inch OD tubing to a male NPT port using a 1/8-27 thread. It provides a reliable, leak-resistant connection in fluid and pneumatic systems where a compression fitting is required on one end and a threaded male NPT interface on the other. Rated to 600 psi maximum working pressure, this connector handles a wide service temperature range from -30 degrees F to 275 degrees F (135 degrees C). It meets ISO 6149 and SAE J1926 standards, making it a conforming choice for systems requiring verified dimensional and pressure performance. Plumbers, HVAC technicians, and industrial pipefitters are the typical installers.

This connector is suited for residential and light commercial fluid conveyance applications, including hydraulic lines, pneumatic control tubing, refrigeration sensing lines, and general plumbing connections where 3/16-inch OD tubing must terminate at a 1/8-27 MNPT port. Its compact brass construction makes it appropriate for tight-space installations in equipment panels, manifolds, and instrument connections. It ships individually and carries a minimum order quantity of one unit.

Key Features

• Brass construction for corrosion resistance in fluid and air service
• 600 psi maximum working pressure rating
• 3/16-inch OD tube compression connection on one end, 1/8-27 MNPT on the other
• Rated from -30 degrees F to 275 degrees F for broad service temperature coverage
• Meets ISO 6149 and SAE J1926 dimensional and performance standards

Compatibility

Designed as an OEM-style compression fitting for systems using 3/16-inch OD tubing terminating at a 1/8-27 male NPT port in fluid or pneumatic service.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or qualified pipefitter. Depressurize and isolate the system completely before removing any existing fittings or installing this connector. Hand-tighten the compression nut onto the tubing, then use an appropriately sized wrench to seat the ferrule — do not overtighten, as brass fittings can deform. Apply thread sealant or PTFE tape to the MNPT threads in accordance with the applicable plumbing or mechanical code before making the threaded connection.
