PATIKIL Flare Gasket 30pcs for 3/8ft Tube 45 Degree - Durable Copper

In this review of the PATIKIL Flare Gasket 30pcs set, the bottom line is simple: this pack is for technicians and hobbyists who need reliable metal-to-metal seals on 45 degree flared fittings and value durable copper construction. Our review found the gaskets do the one job expected of them-create a tight seal on 3/8' OD tubing-thanks to smooth surfaces, good ductility and corrosion resistance. They are sold in a 30-piece kit that fits common HVAC and refrigeration tasks and eliminates repeated trips for small sealing rings.

Key Features

• Material: Made from quality copper, the gaskets resist wear and maintain a firm seal under normal HVAC and refrigeration conditions.
• Size fit: Designed for a 3/8' tube OD, the specified outer and inner diameters provide a snug fit for standard 45 degree flare connections.
• Quantity: The 30-piece pack gives technicians enough spares to complete multiple connections without sourcing individual rings.
• Surface finish: Smooth, burr-free surfaces promote a reliable metal-to-metal seal and reduce the chance of leaks at flared joints.
• Compatibility: Can be used with brass, aluminum and flared copper tubing commonly found in air conditioner and refrigeration systems.
• Corrosion resistance: Copper composition offers good resistance to corrosion and deformation for long-lasting service.

Who It's For

This product is aimed at HVAC installers, refrigeration technicians and DIYers who routinely work with 45 degree flared fittings on 3/8' tubing and need affordable replacement gaskets in bulk. Its copper construction and smooth finish suit maintenance and repair tasks where a reliable metal-to-metal seal matters.

Those who should look elsewhere include users needing gaskets for non-flared fittings, different tube diameters, or specialty alloys; also anyone who requires pre-assembled fittings rather than loose gaskets should choose a complete fitting instead.

Pros & Cons

Pros

• Durable copper material provides wear resistance and good ductility for repeated use.
• Pack of 30 reduces downtime by providing enough gaskets for multiple jobs or spares.
• Smooth, burr-free finish helps form an effective metal-to-metal seal on flared joints.

Cons

• Only suitable for 3/8' tube OD and 45 degree flares, so it is not universal for other sizes or flare angles.
