This rear AC block kit is a purpose-built replacement fitting set made from aluminum and supplied with new O-rings and sealing washers. It is intended to seal the dual-male block style connections used on specific Ford Expedition, Lincoln Navigator, Ford Flex and Explorer model years. The kit comes complete with two block fittings and the sealing hardware needed for a straightforward swap when the original fittings need replacement or temporary closing of the rear AC lines.

Which vehicles and years are compatible with this block off kit?

This kit is designed for vehicles that use the dual male block fitting with an O-ring and sealing washer on the rear AC lines. Specifically, it fits Ford Expedition and Lincoln Navigator models from 2007 onward, and certain Ford Flex and Explorer models from 2010 and later that use the same dual-male connection style.

• Fits Ford Expedition 2007–current with dual-male block rear line fittings
• Fits Lincoln Navigator 2007–current with matching connection type
• Fits Ford Flex 2010+ and Ford Explorer 2010+ that use dual O-ring block fittings
• Not compatible with single O-ring block fittings without sealing washer

How do I identify the correct rear fitting on my vehicle?

Inspect the rear AC line connection to see if it uses a dual male block fitting paired with O-rings and a sealing washer. If the original fitting has a single O-ring or lacks a sealing washer, this kit will not be the correct match.

• Look for two male studs in the block-style connector on the rear AC line
• Confirm presence of O-rings plus a separate sealing washer around the studs
• Compare the existing part to images of dual-male block fittings before purchase
• When in doubt, consult a parts diagram or a technician for verification

What does the package include and what materials are used?

The package contains two aluminum block fittings, replacement O-rings and sealing washers so you can complete a pair of rear line connections. The aluminum body offers corrosion resistance while the supplied seals ensure a tight, leak-resistant mating with the vehicle's existing components.

• 2 aluminum block off fittings manufactured for rear AC lines
• New O-rings sized for the dual-male studs
• Sealing washers included to recreate the original seal design
• Condition: New, ready for installation or spare parts use

Can I install this myself or should a technician do it?

Installation can be performed by a knowledgeable DIYer familiar with refrigerant line work, but because it involves sealed AC components you should follow safety steps and local regulations. If refrigerant needs to be recovered or the system opened beyond the block fittings, professional service with proper equipment is recommended.

• Basic hand tools typically required for removal and reinstallation
• Replace O-rings and sealing washers during installation for best sealing
• Do not attempt refrigerant recovery or charging without certified equipment
• Professional installation recommended for full-system service or leak testing
