P610049 - Textron Aviation OEM Polyethylene Tube

P610049 – Textron Aviation OEM Polyethylene Drain Tubing

Available now on the Airparts.aero Marketplace.

Overview

The P610049 is a genuine Textron Aviation Original Equipment Manufacturer (OEM) bulk polyethylene tubing, specified for the fabrication of low-pressure drain lines in a wide variety of aircraft. This is not a hose for pressurized systems; it is a lightweight, flexible tubing engineered specifically for non-critical, gravity-fed drain applications, such as for air conditioning condensate and door seal drainage.

As a genuine Textron Aviation part, the P610049 is manufactured from the precise grade of polyethylene required to provide the correct balance of flexibility, durability, and resistance to environmental factors. Using the OEM-specified tubing ensures a correct fit with factory drain masts and fittings, and guarantees the material's performance over its service life, preventing the cracking and kinking that can occur with non-certified materials. This product is typically sold by the foot.

Key Features

• Genuine Textron Aviation OEM Part: Guarantees the part is fabricated to the exact Textron engineering drawing for material, diameter, and wall thickness, ensuring a perfect fit.

• Flexible Polyethylene Material: Manufactured from a specific grade of Polyethylene (PE), offering excellent flexibility for routing through complex airframe structures without kinking.

• Designed for Low-Pressure Drains: Specifically intended for gravity-fed, non-critical water drain applications.

• Lightweight Construction: Polyethylene is an extremely lightweight material, contributing to weight savings compared to rubber or metal tubing.

• Water and Corrosion Resistant: The material is inherently waterproof and resistant to the corrosion and microbial growth that can occur in drain systems.

Aircraft Compatibility

This OEM drain tubing is the specified material for fabricating various drain lines on a vast range of Textron Aviation aircraft.

• Primary Textron Aviation Platforms:

  • Cessna Piston Aircraft (100, 200, 300, 400 Series)

  • Cessna Caravan Series

  • Cessna Citation Business Jets

  • Beechcraft and Hawker models

Note: Verification of applicability is the absolute responsibility of the installer. The aircraft's current Illustrated Parts Catalog (IPC) for its specific serial number is the final authority for confirming part number eligibility for a specific drain line application.

Applications

• Fabrication of drain lines for air conditioning evaporator pans and condensate collection systems.

• Door and window seal drainage lines.

• Galley and lavatory water system drain lines.

• In some cases, used as a protective, anti-chafe sleeve over wiring or other lines.

• WARNING: Not for use with any petroleum-based fluids (fuel, oil, hydraulic fluid), in any pressurized system, or for pitot-static lines.

Why Choose P610049?

While a simple component, a clogged or cracked drain line can lead to water accumulation within the fuselage, resulting in hidden corrosion, damage to avionics, or contaminated carpets and interiors. The genuine Textron OEM P610049 tubing is guaranteed to have the correct diameter for a secure fit on factory fittings, and the correct material properties to resist kinking and age-related brittleness. Using a non-certified tube can lead to improper drainage, blockages, or premature failure, creating more significant maintenance issues in the long term.

The selection of Polyethylene (PE) for the P610049 tubing is a specific material science choice for its application. PE is a semi-crystalline thermoplastic from the polyolefin family. Its molecular structure consists of long, simple chains of ethylene monomers, which gives it an excellent resistance to polar solvents, most notably water (H2​O), making it ideal for drain lines. The grade used for this application is likely Low-Density Polyethylene (LDPE), which is characterized by a high degree of branching in its polymer chains. This branching prevents the chains from packing tightly together, resulting in a lower crystallinity and density. From a mechanical properties standpoint, this lower density translates into excellent flexibility and a soft, pliable nature, which is critical for a drain tube that must be routed by hand through the intricate passages of an airframe without kinking or requiring a large bend radius.

Note: This is bulk tubing material sold by the foot. Installation must be performed by a certified A&P mechanic. The tubing must be routed to ensure a continuous downhill path for proper gravity draining. Care must be taken to avoid creating low spots where water could become trapped and freeze at altitude, which could block the line and cause water to back up into the aircraft. Secure the tubing with appropriate clamps to prevent chafing against the airframe structure.
