Jomar 102-654g Brass Ball Valve 3/4 in Full Port Drain

Product Description

The JOMAR 102-654g is a 3/4-inch, two-piece brass ball valve built for full-port flow with a compression connection end and an integrated drain. Rated at 600 WOG (Water, Oil, Gas), this valve handles demanding pressure applications across a wide range of trade service work. The full-port bore minimizes pressure drop, keeping flow rates consistent through the valve body. Plumbers and pipefitters install this type of valve as a reliable shutoff on water supply lines, compressed air systems, and fuel gas piping where a low-restriction, serviceable isolation point is required.

This valve is suited for residential and light commercial plumbing applications where a compression-style connection is preferred or required. The two-piece body design allows the valve to be serviced or the ball replaced without removing the entire valve from the line. The integrated drain port provides a convenient bleed point for depressurizing or draining a section of pipe during maintenance, making it a practical choice for mechanical rooms, boiler rooms, and utility installations.

Key Features

• Full-port bore for minimal flow restriction and pressure drop
• 600 WOG pressure rating suitable for water, oil, and gas service
• Compression connection ends for tool-accessible, solder-free installation
• Two-piece body construction allows in-line service and ball replacement
• Integrated drain port for line bleed-down during maintenance
• Brass body construction for corrosion resistance in wet service environments

Compatibility

Designed as an OEM-style replacement or direct-install brass ball valve for 3/4-inch compression connection piping systems in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and depressurize the line completely before removing or installing the valve. Compression fittings require proper ferrule seating and appropriate torque on the compression nut — avoid over-tightening, which can deform the ferrule and cause leaks. Verify the 600 WOG rating is appropriate for the operating pressure and media of the specific system before placing the valve in service.
