PQY V-Band Clamp Quick-Release Intercooler Connector 3" — Aluminum, 800 psi Seal

The PQY 3" quick‑release aluminum V‑band clamp is a removable, high‑pressure intercooler/turbo inlet connector that creates a reliable, leak‑resistant union for custom intake and charge‑air piping.

If you build or service turbo, supercharged, or custom intake systems, this PQY quick‑release V‑band clamp flange gives you a compact, serviceable joint that simplifies assembly and disassembly. Designed as a kit with an aluminum band and weldable ferrules, a rubber union sleeve, and an O‑ring seal, it replaces bulky or harder‑to‑service couplings and is sized for 3" piping. The clamp is engineered to withstand demanding pressurized air use in performance and racing environments while allowing easy removal when you need to access intercoolers, throttle bodies, or turbo components.

How does this clamp handle pressure and heat in boosted systems?

The PQY clamp assembly uses a solid aluminum band, matching ferrules, and an elastomer seal to contain boost pressures up to 800 psi and temperatures up to 400°F. Those ratings ensure the joint remains secure under heavy load and elevated under‑hood temperatures typical of racing or tuned engines. The O‑ring provides a positive seal between the flanges while the rubber sleeve smooths any minor misalignment.

• Rated working pressure: 800 psi
• Maximum temperature rating: 400°F
• Includes O‑ring gasket for a sealed flange interface
• Aluminum ferrules and band resist corrosion and are lightweight

What components are included and how should I prepare them for welding?

The kit contains an aluminum quick‑release band with a locking pin, two aluminum weld ferrules, a rubber union sleeve, and a rubber seal O‑ring. For durable welding, remove the clamp band and install the ferrules onto your pipe, perform the welds, and allow the assemblies to cool completely before reinstalling the O‑ring and clamp. This prevents heat damage to the elastomer seal and prolongs service life.

• Included parts: clamp band with locking pin, ferrules, rubber sleeve, O‑ring
• Weld ferrules to piping then cool fully before reassembly
• Avoid welding while the O‑ring is installed to prevent melting
• If pin is missing, contact PQY for replacement support

Which sizes are available and how do I pick the right one?

PQY offers this quick‑release V‑band clamp in multiple diameters so you can match the clamp to the outside diameter of your intercooler or intake piping. This specific listing is for the 3" version; other common sizes include 2", 2.5", 2.75", 3.5", and 4" to suit a broad range of builds. Always measure the mating flange outside diameter and choose the matching clamp size to ensure a proper fit and seal.

• Available sizes: 2", 2.5", 2.75", 3", 3.5", 4"
• Measure flange outside diameter before ordering
• Can be welded directly to tubing or used with compatible flanged parts
• Pinless clamp variants also available from PQY

How does the quick‑release design help during maintenance or upgrades?

The quick‑release V‑band latch lets you separate sections of intake or charge piping rapidly without cutting, unbolting multiple fasteners, or dealing with heavy hardware. That saves time when swapping intercoolers, removing turbo outlets, or diagnosing boost leaks. The system’s clamp also returns to consistent alignment after each reassembly, simplifying repeat service tasks.

• Fast disconnect for quick component removal
• Reassembles with consistent fit and alignment
• Useful for racing, tuning, and frequent maintenance
• Compact profile reduces bulky hardware in tight engine bays

Who this is for: This PQY 3" quick‑release V‑band clamp is aimed at DIY engine builders, performance tuners, and motorsport mechanics who need a lightweight, serviceable clamp for intercoolers, turbo inlets, and custom intake piping. It’s ideal when you require a robust, weldable flange solution with high pressure and temperature capability and the convenience of rapid disassembly.
