QS200M24S - Aerospace Clamp

QS200M24S – J&M Products Quick-Seal® V-Band Clamp

Available now on the Airparts.aero Marketplace.

Overview

The QS200M24S is a high-performance, latch-style V-band clamp from J&M Products, Inc., a leading OEM manufacturer of aerospace ducting and coupling components. This is not a simple hose clamp; it is a precision-engineered structural fastener designed to join flanged tubing and components in critical, high-pressure, and high-temperature aircraft systems. Its primary application is in Environmental Control Systems (ECS) for connecting bleed air ducting, as well as in anti-ice, hydraulic, and fuel systems.

The clamp's design utilizes the mechanical principle of a wedge. The 360-degree V-shaped retainer mates with the flanges of the two ducts to be joined. When the T-bolt latch is tightened, the V-retainer draws the flanges together with a massive and uniform radial force, creating an exceptionally strong and rigid, sealed joint. The Quick-Seal® T-bolt latch design allows for rapid and repeated installation and removal, significantly reducing maintenance time compared to multi-bolt flanges.

Key Features

• OEM Certified: A genuine J&M Products clamp, manufactured to the highest aerospace quality and performance standards.

• Quick-Seal® Latch: Features a robust T-bolt and trunnion style latch for quick, easy, and reliable fastening and removal.

• V-Band Coupling Design: Provides a strong, lightweight, and rigid structural connection for flanged tubes and components.

• Corrosion-Resistant Steel Construction: The band and latch components are fabricated from 300-series corrosion-resistant steel (CRES) for durability and long service life.

• High-Strength Fastener: Utilizes a high-tensile T-bolt and a silver-plated, all-metal self-locking nut, suitable for high-temperature and high-vibration environments.

Aircraft Compatibility

• Universal Aerospace Application: V-band clamps of this type and size are used extensively across all categories of aircraft where rigid, flanged ducting is employed. This includes:

  • Commercial Transport (Boeing, Airbus)

  • Business & Corporate Jets (Gulfstream, Bombardier, Dassault, Textron Aviation)

  • Military Aircraft

  • Regional Jets (Embraer, Mitsubishi)

Note: The correct clamp part number for any application must be verified against the aircraft's specific Illustrated Parts Catalog (IPC) or maintenance manual.

Applications

• ECS Bleed Air Ducting: The primary application for connecting high-pressure, high-temperature (up to 800°F) pneumatic ducts from the engine or APU to the air conditioning packs.

• Anti-Ice Systems: Connecting ducting for wing and engine cowl anti-ice systems.

• Fluid Systems: Joining flanged tubing in high-pressure hydraulic or fuel systems.

• Exhaust Systems: Used in the exhaust systems of some auxiliary power units (APUs) and smaller turbine engines.

Why Choose QS200M24S?

The failure of a clamp on a bleed air duct can be catastrophic. Such a failure would release extremely hot (600-800°F), high-pressure (40-50 PSI) air into a confined nacelle or fuselage compartment, which can lead to an immediate fire, severe damage to surrounding wiring and structures, and potential loss of aircraft control. The J&M Products QS200M24S is a certified, OEM-quality clamp with guaranteed material strength, manufacturing quality, and traceability. Using a non-certified, "will-fit," or damaged clamp introduces an unacceptable risk. For the safety and integrity of critical aircraft systems, there is no substitute for a genuine, certified V-band clamp.

The engineering principle that makes the QS200M24S V-band clamp exceptionally effective is the conversion of tangential force into radial force through the mechanical advantage of a wedge. The V-shaped retainers of the clamp act as a continuous 360-degree wedge that engages the duct flanges. The tensile force (Ft) generated in the clamp's band by the torqued T-bolt is translated into a significantly larger, uniformly distributed radial clamping force (Fr) that pulls the flanges together. This relationship is governed by the V-angle (α), where the radial force is proportional to Ft​/tan(α)

. This immense radial force not only creates a rigid structural joint capable of withstanding axial pressure and bending moments but also provides the necessary load to compress the metallic seal often used between the flanges, creating a secure, zero-leak connection for high-energy fluids and gases.

Note: The QS200M24S is a flight-critical fastener. Installation must be performed by a certified A&P mechanic. It is absolutely critical that the nut be tightened to the specific torque value called out in the aircraft maintenance manual using a calibrated torque wrench. An under-torqued clamp will leak and fail. An over-torqued clamp can cause the bolt or band to yield, leading to a catastrophic failure. Inspect clamp for any signs of damage, cracking, or distortion before installation.
