Infinity Straight Female Adapters

Infinity Straight Female Adapter (NPT)

The Secure Bridge Between Tubing and Threaded Equipment

Connect your Infinity Aluminum Pipe directly to male-threaded equipment with the Infinity Straight Female Adapter. This fundamental fitting features a push-to-connect grab ring on one side to accept the tubing, and a Female NPT thread on the other.

This adapter is the standard solution for transitioning from rigid threaded pipe (like galvanized or black iron) to the modern Infinity system. It is also essential for connecting your air lines to the outlets of compressors, dryers, and hard-piped ball valves.

Two Materials, One Reliable Connection

1. Nickel-Plated Brass (20mm – 63mm)

For standard shop lines, the brass adapter ensures a rugged, corrosion-resistant link.

• Push-to-Connect: Features the patented Infinity stainless-steel grab ring. Simply push the cut pipe end into the fitting for an instant, permanent lock.
• Heavy-Duty Threads: The precision-machined female NPT threads allow for a tight, leak-free seal against male pipe nipples or valve stems.
• Corrosion Protection: The nickel plating matches the aluminum pipe and prevents the oxidation common with raw brass fittings.

2. Die-Cast Aluminum (80mm – 168mm)

For industrial mainlines, the aluminum adapter provides a lightweight, high-strength transition.

• Industrial Grip: Utilizes the heavy-duty clamp or flange-style retention system to secure the large-diameter pipe against high-pressure blow-out forces.
• Direct Transition: Ideal for connecting large 3″, 4″, or 6″ aluminum mains to the male threaded outlets of large receivers or filtration banks.

Key Features & Benefits

• Transition from “Old” to “New”: This is the “starter” fitting often used to convert an existing steel pipe system into an Infinity aluminum extension. Screw it onto the old steel threads, push in your new aluminum pipe, and you are ready to go.
• 100% Leak-Free:

The tubing side uses a double-seal mechanism (NBR seals) to prevent air loss, while the threaded side provides a solid platform for applying thread sealant or tape for a perfect seal.

• Full-Bore Flow: Designed to minimize restriction, ensuring that air flows smoothly from the threaded component into the tubing without a significant pressure drop.

• Retrofits: connecting a new aluminum drop to an old galvanized steel header.
• Valve Installation: Connecting to the male ends of isolation valves or bypass assemblies.

Make the switch to aluminum seamless. Use the Infinity Straight Female Adapter for a solid, leak-free transition.
