CCA-1550 – Curtis Pipe Thread Quick Drain Valve

Available now on the Airparts.aero Marketplace.

Overview

The Curtis Superior Valve CCA-1550 is a precision-engineered quick drain valve designed to simplify fluid servicing on a wide range of general aviation aircraft. This FAA-PMA approved valve replaces the standard drain plug on engine oil sumps, fuel tanks, and hydraulic reservoirs, transforming a typically messy task into a clean, quick, and safe procedure. Manufactured from high-quality brass and featuring robust internal components, the CCA-1550 provides a positive, leak-proof seal and is built to withstand the harsh thermal and chemical environment of aircraft operations. It is an essential, time-saving upgrade for any aircraft owner or maintenance facility.

Key Features

• Positive Action Sealing: Features a spring-loaded actuator that requires a deliberate push-and-turn motion to open, preventing accidental drainage from vibration or impact. The valve remains securely closed under all normal operating conditions.
• Superior Materials: Constructed from a solid brass body for exceptional durability and corrosion resistance. Internal components include a stainless steel spring and ball for long-term reliability.
• High-Performance Seal: Equipped with a Viton® (Fluorocarbon) O-ring seal, providing superior resistance to high temperatures, engine oil, 100LL Avgas, jet fuel, and hydraulic fluids.
• FAA-PMA Certified: Proudly manufactured in the USA and approved under FAA Parts Manufacturer Approval (PMA), guaranteeing the highest standards of quality, safety, and airworthiness.
• Damage Prevention: Eliminates the repeated removal and re-torquing of the standard drain plug, preventing wear, cross-threading, or stripping of the threads on the expensive engine oil sump or fuel tank.

Aircraft & Engine Compatibility

The Curtis CCA-1550 is compatible with any engine, fuel tank, or fluid reservoir equipped with a standard 1/2"-14 NPT drain port. This is a common size for the oil sumps on many popular aircraft engines. Always verify the drain plug size on your specific application before ordering.

• Engine Manufacturers:
  • Lycoming (many models in the O-320, O-360, IO-360, O-540, IO-540 series)
  • Continental (many models in the O-300, O-470, IO-470, IO-520, IO-550 series)
• Airframe Applications:
  • Engine Oil Sump Drain
  • Fuel Tank Sump / Fuel Strainer Drain
  • Hydraulic Fluid Reservoir Drain

Applications

The CCA-1550 quick drain valve is a mission-critical tool for enhancing maintenance efficiency:

• Routine Oil Changes: Allows for rapid, tool-free draining of engine oil directly into a container, significantly reducing service time and cleanup.
• Pre-Flight Sumping: Facilitates quick and clean pre-flight fuel sampling from main tanks or gascolators.
• Fluid Servicing: Simplifies the draining of hydraulic fluids during system maintenance and overhauls.

Why Choose CCA-1550?

The Curtis CCA-1550 is not just a convenience item; it is a smart investment in your aircraft. It drastically reduces the risk of costly damage to your engine's oil sump threads, a common and expensive repair. The robust, all-metal construction and FAA-PMA approval provide confidence and peace of mind that you are installing a safe, certified, and reliable component. For any mechanic or owner who performs their own oil changes, the CCA-1550 pays for itself in saved time, labor, and supplies after just a few uses.

The Curtis Superior Valve model CCA-1550 is a fundamental component for any maintainer focused on efficiency and preventative maintenance. Its 1/2"-14 NPT thread specification makes it a direct-fit replacement for the AN910-8D or MS20910-8D standard drain plugs found on a vast number of general aviation powerplants. The valve's internal mechanism, featuring a stainless steel spring and ball mated to a Viton® seal, creates a positive, leak-proof barrier that is impervious to the degrading effects of aviation fluids and temperature cycling. By installing a CCA-1550, you are not only improving the serviceability of the aircraft but also enhancing its safety by providing a secure, lockable drain point that is less susceptible to failure than a repeatedly used standard plug and crush washer. At Airparts.aero, we provide these essential, certified components to ensure your maintenance operations are as safe and efficient as possible.

Note: Always use an appropriate thread sealant (e.g., Titeseal) on the NPT threads during installation. Do not use Teflon tape. Install in accordance with the manufacturer's instructions and all applicable aviation maintenance practices. Verify thread size of the intended port before purchase.
