Prevost 1/4″ Male/Female Coupler Industrial Body Set (Plugs Included)

• Upgrade your air line with the Prevost 1/4″ Industrial Body Coupler Set. Engineered to replace standard, leaky brass fittings, this premium coupler system combines lightweight composite materials with a patented “one-touch” safety mechanism.¹ Designed for the harsh demands of automotive and industrial environments, it eliminates the risk of hose whip while ensuring a perfect, leak-free seal every time you connect.²

  This set features the universal Industrial Interchange (Mil-Spec C-4109) profile, making it fully compatible with your existing 1/4″ industrial-style plugs and tools.

  Key Features

  • Zero-Pressure Safety Disconnect (Anti-Hose Whip):

  Protect your team and equipment. The patented 2-stage release button automatically vents downstream pressure before disconnecting the tool.3 This eliminates dangerous “hose whip” and makes changing tools effortless, even under full pressure.4

  • Non-Marring Composite Body:

  Unlike heavy metal couplers that can scratch, dent, or chip painted surfaces, the Prevost ISI body is made from a high-grade, impact-resistant composite.5 It is tough on the inside but safe to drag over car hoods, finished wood, or delicate machinery.

  • Leak-Free Technology:

  Stop hearing money hiss away. The precision-engineered Nitrile O-ring seal ensures an airtight lock that prevents pressure drops, helping your compressor run less often and extending the life of your air tools.6

  • Ergonomic & Lightweight:

  Weighing significantly less than traditional steel or brass couplers, this system reduces operator fatigue during long shifts. The textured body provides a sure grip, even with greasy or gloved hands.

  • Universal Industrial Compatibility:

  Designed to accept all standard 1/4″ Industrial Interchange (M-Style) plugs. Whether your setup requires Male (MNPT) or Female (FNPT) thread connections, this system integrates seamlessly into your current air drops and hose lines.
