3mirrors A/C Block Off Kit for 2004–2011 Dodge Grand Caravan & Chrysler Town & Country — Stainless Steel CNC Fittings with HNBR O‑

If the rear air conditioning circuit or evaporator in your Caravan or Town & Country is leaking or has been removed, this kit provides a clean, serviceable way to close off the rear lines so the front A/C continues to function without refrigerant loss. The kit replaces factory connections with threaded stainless fittings and uses HNBR O-rings that withstand higher temperatures and resist degradation compared with standard seal compounds.

How does this kit let my front A/C keep working after the rear system is removed?

The block-off kit replaces the open rear service ports with sealed threaded fittings, preventing refrigerant from escaping from the rear lines or evaporator. With the rear circuit isolated, the front compressor and evaporator remain charged and operational, so you avoid needing a full rear-system rebuild.

• CNC-machined stainless fittings that thread into the factory hose ends.
• HNBR O-rings included for durable, temperature-resistant sealing.
• No cutting or permanent modification of front A/C lines required.
• Simple disconnect and install procedure—basic instructions included.

Will these parts fit my vehicle and what models are supported?

This kit is intended for many 2004–2011 Dodge Grand Caravan and Chrysler Town & Country vehicles; it matches the common rear A/C line thread sizes used on those platforms. However, variations exist, so verify your vehicle’s line sizes before purchasing to ensure compatibility.

• Designed as a direct replacement for commonly used rear line connections.
• Includes M20 x 1.5 and M22 x 1.5 stainless bolts for typical fittings.
• Check original hose fitting threads prior to installation.
• Seller support available for fitment questions.

What materials and components are included, and why do they matter?

The kit ships with CNC-machined stainless steel nuts and bolts, and HNBR O-rings formulated for refrigerants like R-134a and R-1234yf. Stainless hardware resists corrosion, and HNBR seals offer better heat and cold resistance, delivering a more reliable long-term seal than standard NBR or Viton in this application.

• 304 stainless steel nuts and bolts to resist rust and wear.
• HNBR O-rings suited for R-134a and R-1234yf refrigerants.
• Precision CNC manufacturing for consistent thread fitment.
• Step-by-step instructions included to guide installation.

How difficult is installation and what tools will I need?

Installation is straightforward for anyone comfortable working on basic auto HVAC lines: disconnect the rear A/C lines, install the supplied fittings with HNBR O-rings, and torque to specification. No permanent cutting or special shop equipment is required, though basic hand tools and a leak test are recommended.

• Disconnect rear lines, remove any old fittings or clamps.
• Install supplied stainless nuts/bolts with HNBR O-rings.
• Hand tools and appropriate wrenches; torque to recommended values.
• Pressure/leak check after installation to confirm seal integrity.
