Jb Industries nft5-4-cj O-ring Seal Cap 1/4 Inch Sae 500 Count

Product Description

The JB INDUSTRIES nft5-4-cj is a bulk jar of 1/4 inch SAE O-ring seal caps designed to protect refrigerant service ports and fittings from contamination, moisture ingress, and debris. Each cap forms a secure seal over standard 1/4 inch SAE fittings, helping maintain system integrity between service calls. The jar format is suited to HVAC technicians and refrigeration pros who need a ready supply on the truck or at the shop without dealing with individually packaged hardware. The 500-count bulk quantity reduces per-unit cost and ensures caps are always available during high-volume service seasons.

These O-ring seal caps are a standard consumable on residential and commercial HVAC and refrigeration service work. Technicians install them on service port fittings after completing refrigerant charging, recovery, or system inspection. The caps help prevent contaminants from entering low-side and high-side ports during the interval between service visits, which is especially important in exposed or outdoor equipment installations.

Key Features

• 1/4 inch SAE fitting size for standard HVAC and refrigeration service ports
• O-ring seal design provides a reliable, moisture-resistant closure
• 500-count bulk jar format minimizes reorder frequency for active service fleets
• Designed for repeated use across residential and commercial service applications

Compatibility

Designed as an OEM-style consumable cap for standard 1/4 inch SAE service port fittings found on residential and commercial HVAC and refrigeration equipment.

Installation Notes

Service port caps are installed by HVAC technicians and refrigeration mechanics after completing system service. Always recover or isolate refrigerant per EPA Section 608 requirements before removing or replacing service port caps. Finger-tighten caps onto the service port fitting until snug; do not use tools that may cross-thread or damage the port. Inspect the O-ring for damage before reuse and replace any cap with a deformed or missing O-ring.
