Jmf Company CAP3/8 Flare Fitting Cap 3/8 Inch Lead Free

Product Description

The JMF COMPANY CAP3/8 is a lead-free brass flare fitting cap sized for 3/8-inch flare connections. Flare caps are used to seal and terminate open flare tubing ends, preventing contamination, pressure loss, and moisture ingress in refrigeration, HVAC, and plumbing lines. The lead-free brass construction meets current potable-water and environmental compliance standards. This fitting is a standard component stocked by HVAC technicians, refrigeration mechanics, and plumbers for capping unused ports or sealing lines during service, storage, or system modification.

This cap is suited for residential and light commercial applications wherever 3/8-inch flare terminations are present. Common install scenarios include capping service ports on refrigerant lines, sealing unused manifold connections, and terminating copper tubing during system decommission or repair. The lead-free designation makes it appropriate for potable-water plumbing applications in jurisdictions that enforce lead-free fitting requirements.

Key Features

• Lead-free brass construction meets current potable-water compliance requirements
• Standard 3/8-inch flare seat for secure, leak-resistant termination
• Seals open flare ends against contamination, moisture, and pressure loss
• Compact cap profile fits standard flare nut wrenches for fast installation

Compatibility

Designed as a standard OEM-style replacement or service fitting for 3/8-inch flare connections in residential and light commercial HVAC, refrigeration, and plumbing systems.

Installation Notes

Installation is performed by licensed HVAC technicians, refrigeration mechanics, or plumbers using standard flare wrenches. Before capping any pressurized line, relieve system pressure and follow applicable recovery procedures for refrigerant lines per EPA Section 608 requirements. Hand-tighten the cap onto the flare fitting seat, then snug with a wrench — do not overtighten brass flare fittings. Inspect the flare seat for damage or debris before seating the cap to ensure a leak-free seal.
