Power Tank 90-Degree Elbow Push-In Air Line Fitting

The Power Tank 90-Degree Elbow Push-In Air Line Fitting is a nickel-plated brass elbow connector designed to route ARB-compatible air lines around corners without kinking or restricting flow. The 1/8" Global thread port accepts all common 1/8" thread standards, and the fitting is available in two push-in tube sizes: 5 mm for older-style ARB air lines and 6 mm for newer-style ARB air lines.

Clean Routing in Tight Spaces

A 90-degree elbow lets an air line change direction at a port or junction without bending the tubing back on itself. In a CO2 system or onboard air setup where regulators, manifolds, and gauges are mounted close together, a straight fitting often forces the line into an awkward arc that stresses the tubing over time. The elbow keeps the line's exit path intentional and tidy, which matters when the system lives in a vehicle's cargo area or under a hood where clearance is limited.

Push-In Connection, No Tools Required

The push-in design seats the air line with a single firm push and releases it by pressing the collet ring. No wrenches, no ferrules, no thread tape on the tube side. For a system that gets broken down and reassembled between trips, or reconfigured when swapping between a CO2 tank and a nitrogen shock-inflation tool, that speed matters. The nickel-plated brass body resists corrosion in the wet and dusty conditions that come with overlanding use.

Universal 1/8" Thread Compatibility

The 1/8" Global thread standard on the port side of this fitting is compatible with NPT, BSPT, RC, NPTF, BSPP, and G thread forms. That covers the thread patterns found on most regulators, gauges, manifolds, and valve bodies used in portable CO2 and compressed-air systems, so the fitting works across a wide range of equipment without requiring a thread adapter.

• Nickel-plated brass construction: corrosion-resistant for outdoor and vehicle use
• 1/8" Global thread port: compatible with NPT, BSPT, RC, NPTF, BSPP, and G thread standards
• Two tube sizes: 5 mm for older-style ARB air lines, 6 mm for newer-style ARB air lines

Specifications

Who This Is For and Isn't

This fitting suits anyone building or servicing a portable CO2, compressed-air, or nitrogen system that uses ARB-compatible air line and needs a 90-degree direction change at a 1/8"-threaded port, including overlanders running Power Tank regulators, gauges, or manifolds where straight fittings would kink the line.

This fitting does not accept push-in tubing outside the 5 mm or 6 mm OD sizes offered, and the port side is limited to 1/8" thread sizes. It will not thread into ports sized larger or smaller than 1/8".

Common Questions

Which size should I choose: 5 mm or 6 mm?

The 5 mm Power Tank elbow fitting is sized for older-style ARB air line, and the 6 mm version is sized for newer-style ARB air line. If you are unsure which generation your ARB line is, measure the outer diameter of the tubing: 5 mm OD is the older standard and 6 mm OD is the newer one.

What thread standard does the 1/8" port use, and will it fit my regulator or gauge?

The port on this 90-degree elbow fitting uses the 1/8" Global thread standard, which is compatible with NPT, BSPT, RC, NPTF, BSPP, and G thread forms. Most regulators, gauges, and manifolds used in portable CO2 and compressed-air systems use one of these 1/8" thread patterns, so the fitting threads in directly without an adapter in the majority of cases.

Does installing or removing the push-in air line require any tools?

No tools are needed on the tube side of this Power Tank push-in elbow fitting. The air line seats with a firm push into the collet and releases by pressing the collet ring inward while pulling the tube out.

What is the fitting body made of, and will it hold up to outdoor use?

The body of this Power Tank elbow fitting is nickel-plated brass. Nickel plating adds a corrosion-resistant surface over the brass substrate, making the fitting suitable for the moisture, dust, and temperature variation that come with vehicle-based and outdoor air system use.
