Parker 3GF-8 Brass Flared Tube Seal Bonnet 1/2 in 45 Deg

Product Description

The PARKER 3GF-8 is a brass seal bonnet designed for use with 1/2 inch OD flared tubing at a 45-degree flare angle. Seal bonnets cap off or terminate a flared tube connection, preventing leakage at open ports in fluid or gas distribution systems. This fitting uses a standard flare end connection, making it compatible with common field tubing setups. The all-brass construction resists corrosion and stands up to the pressure and temperature ranges typical of HVAC refrigerant lines, hydraulic circuits, and fuel gas applications. Plumbers, HVAC technicians, and pipefitters are the primary installers of this type of fitting.

This seal bonnet is suited for residential and light commercial applications where a 45-degree flare port needs to be capped or sealed. Typical scenarios include capping unused ports on manifolds, valve bodies, or distribution blocks. The 1/2 inch tube OD sizing corresponds to a standard flare fitting dimension found throughout refrigerant, fuel, and hydraulic tubing systems. It is sold individually but requires a minimum order quantity of 5 units per transaction.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or pipefitters. Before installing or removing any fitting, shut off and depressurize the system completely. Flare fittings should be inspected for damage or scoring on the seating surface before assembly. Refer to applicable codes such as IFGC or ASHRAE standards for torque and assembly requirements specific to the system being serviced.
