Compressed Air Couplings – Safe, Fast Connections for Your Air System

Keeping your compressed air system reliable starts with the small parts that get used and abused every day. Compressed air couplings are one of those components: they live on hoses, drops, and tools, and if they leak, stick, or fail, your whole system feels it. This collection pulls together the couplers, plugs, and manifolds you actually want to run in a real shop or plant, with a strong focus on Prevost safety couplings plus select options from other proven brands.

Why quality couplings matter

Well-spec’d pneumatic couplers do more than just “connect a hose”:

• Maintain a tight seal to prevent air leaks and lost CFM
• Allow quick connect / disconnect even under pressure
• Reduce dangerous hose whip when disconnecting
• Protect tools, hoses, and fittings from shock loads
• Cut downtime caused by worn-out, mystery-brand fittings

Use this collection when you’re standardizing your shop on one coupling style, upgrading older fittings, or building a new air system from scratch.

Prevost couplings – our primary solution

Most of our coupling sales run through Prevost for a reason. Their prevoS1 safety quick couplings have become a global benchmark for compressed air connections, combining push-button ease with serious safety engineering.

Typical Prevost coupling features you’ll see in this collection include:

• One-push safety disconnect that depressurizes before release to tame hose whip
• Composite bodies that are impact-resistant, non-marring, and comfortable to handle all day
• High-flow internal bores for tools that are hungry for air (spray guns, grinders, blast cabinets, etc.)
• Resistance to abrasion, vibration, corrosion, and crushing in tough shop environments
• Matching plugs and manifolds so you can build a clean, leak-free system end-to-end

You’ll find industrial (M-style), automotive, and ARO-style profiles, along with high-flow prevoS1 couplers for lines where every CFM counts. Many options are push-to-connect and can be operated with one hand, even with gloves on.

Other brands and profiles in this collection

While Prevost is our mainstay, Warthog Air also stocks other reputable brands and styles so your whole system can be standardized in one order. In this collection you’ll see:

• Quick-connect air hose couplings and plugs in popular body sizes (¼", ⅜", ½")
• Matching male and female plugs for tools, manifolds, and hose ends
• Universal or multi-profile couplers where you need to support multiple plug types
• Manifolds and wall plates that bring several couplers to one drop location
• Couplings intended for low-pressure pneumatic use up to typical shop ratings

If you’re converting a mixed shop with different plug styles, grab a few extra plugs and a manifold or two to build clean transition points instead of living with adapters forever.

How to choose the right coupling (quick checklist)

Use this simple process when picking couplings from the collection:

1. Match the profile

• Decide whether you’re standardizing on industrial (M-style), automotive, ARO, or a specific high-flow profile.

2. Pick the body size

• ¼" body for light tools and general shop air
• ⅜" or ½" body for higher-CFM tools and long hose runs

3. Check your thread and hose sizes

• Confirm NPT thread size and hose ID so everything threads and clamps up cleanly.

4. Decide on safety features

• For production work or shared shop spaces, choose safety quick couplers with controlled depressurization (such as prevoS1).

5. Consider the environment

• For harsh or mobile environments, favor composite or corrosion-resistant bodies and sealed designs that resist dust and moisture.

Where these couplings fit in your system

The couplings in this collection are at home on:

• Hose reels and drop legs in shops and garages
• Header manifolds along your main air pipe runs
• Portable compressor hoses and whip leads
• Direct tool connections where frequent changeovers happen

Pair Prevost couplings with quality hose, filters, and regulators, and you’ll feel the difference immediately: fewer leaks, faster tool changes, less noise, and a safer work area.

Browse the couplings in this collection, standardize your profiles, and get your compressed air connections sorted the way a serious shop should. If you’re not sure which profile or body size to commit to, build your first station around Prevost and expand from there—your tools, hoses, and crew will notice the upgrade.
