Flylock Stainless Steel 3/8-in NPT Quick Connect Plug – 2-Pack, 5000 PSI

Overview

Meet the Flylock 3/8-in stainless steel quick coupler plug—a compact, heavy-duty connector built to handle demanding high-pressure tasks. Crafted from stainless steel, it resists chemical exposure and regular wear, helping you maintain a reliable seal during repeated exchanges. Its sturdy form fits seamlessly into your existing 3/8" systems and supports efficient tool swaps on the job or in the shop.

Why this matters

In setups where hoses, pumps, and attachments are frequently connected and disconnected, a repeatable, solid connection matters. This plug converts a 3/8" male quick disconnect to a 3/8" male NPT, giving you flexible options for pressure washer configurations up to 5000 PSI.

• Working pressure up to 5000 PSI supports intense cleaning and automotive tasks
• Chemical-resistant stainless steel extends life in routine washdowns
• Fits 3/8" female QC fittings or 3/8" female pipe threads for broad compatibility

What’s included

• Two 3/8-Inch FPT stainless steel quick coupler plugs
• Designed for durability and repeated use across harsh environments
• Compatible with pressure washer accessories, water pumps, hose reels, ball valves, telescoping wands, surface cleaners, and spray guns

How to use

Thread the plug into a 3/8" female QC or NPT connection to secure a tight seal, then pull apart for a quick disconnect when you’re ready to switch tools. A steady, predictable fit helps speed up transitions.

Care and maintenance

• Rinse after exposure to detergents or solvents
• Dry thoroughly and inspect threads regularly
• Avoid overtightening to preserve seal integrity
