MS22064-5 – Textron Aviation / Military Standard Steel Single-ear Spring-Tension Band Clamp
Available now on the Airparts.aero Marketplace.
Overview
The MS22064-5 is a military-standard, single-ear, spring-tension hose clamp designed for creating a reliable, 360-degree seal on fluid and pneumatic hoses in a variety of aerospace applications. Unlike common worm-drive clamps, the MS22064-5 is engineered to provide a consistent, uniform clamping pressure that automatically adjusts to the thermal expansion and contraction of the hose and fitting. Manufactured from high-quality steel with a protective finish, this clamp is a lightweight, tamper-resistant, and vibration-proof solution for securing critical hose connections.
Key Features
- Constant Tension Design: As a spring-tension clamp, it maintains a constant clamping force on the hose assembly. This feature allows it to compensate for changes in temperature and hose material compression, ensuring a leak-free seal over time.
- 360-Degree Stepless Seal: The smooth, uninterrupted inner band provides uniform compression around the entire circumference of the hose, eliminating the gaps and steps found on traditional worm-gear clamps. This prevents leaks and damage to the hose material.
- Tamper-Proof & Vibration Resistant: Once installed and crimped with the proper tool, the clamp creates a permanent, non-releasable connection that is extremely resistant to loosening from engine or airframe vibration.
- High-Quality Materials: Fabricated from high-strength steel and treated with a durable phosphate and zinc coating. This provides excellent corrosion resistance, ensuring the clamp's integrity in the demanding aircraft environment.
- MS Certified Standard: Manufactured in strict accordance with the MS22064 military specification, guaranteeing its material, dimensions, and performance are certified for airworthy applications.

Aircraft Compatibility
The MS22064-5 is a versatile clamp used across many aircraft platforms, including those manufactured by Textron Aviation (Beechcraft). It is often specified as a direct replacement or alternative to other clamp types in certain applications.
- Common Applications:
- Fluid & Air Lines: Securing hoses for low-pressure hydraulic return lines, pneumatic systems, and engine vent lines.
- Drain Lines: Used on various system drain hoses where a permanent and reliable seal is required.
- Wire Harness Protection: Securing protective boots and sleeves over wiring and connectors.
- Known Aircraft Usage (non-exhaustive):
- Beechcraft Baron: B55, E55, 58
- Beechcraft King Air: B200 Series
Applications
The MS22064-5 clamp is the superior choice for specific, permanent installations:
- Flexible Hose Connections: Ideal for securing soft-walled silicone, rubber, or neoprene hoses to rigid fittings, as the spring tension prevents damage from over-torquing.
- Maintenance-Free Joints: Its permanent, tamper-proof installation makes it perfect for "fit-and-forget" connections in areas that are not frequently serviced.
- Uniform Sealing: Essential for applications where preventing any fluid weep or air leak is critical for system performance and safety.
Why Choose MS22064-5?
For securing low-pressure hoses, the MS22064-5 provides a more reliable and lighter-weight solution than traditional clamps. Its ability to dynamically adjust to temperature changes ensures a consistent seal where other clamps might loosen over time. By using a genuine MS-standard part, you are guaranteeing that the clamp has the correct material properties and clamping force range specified by aircraft engineers. For a secure, permanent, and airworthy hose connection, the MS22064-5 is the professional, engineered choice.

The MS22064-5 clamp functions based on the principle of plastic deformation. Installation requires a specialized pincer tool that uniformly closes the clamp's single "ear." As the ear is crimped, the band diameter is reduced, applying a predictable spring force to the hose. This design ensures that the clamping pressure is consistent and repeatable, independent of operator feel. The smooth, edgeless inner band concentrates this pressure evenly around the hose, creating a superior seal without cutting into the hose material. This makes it particularly effective on thin-walled or soft hoses where the sharp edges of a perforated worm-drive clamp could cause damage.
