The CarRundown verdict.
The LH04 suits drivers who already own a compatible tire inflator and want a longer hose with a right-angle lock-on chuck at the valve. Fanttik lists a 19.96-inch length, a 0.305-inch × 32 TPI connection and a maximum working pressure of 200 PSI; these are manufacturer specifications, not CarRundown measurements. The product page listed its exact Default Title variant at $17.99 USD on October 24, 2026, and displayed no LH04-specific code. Check the exact pump connection and pressure limits before adding this small accessory.
Fanttik’s LH04 is an extension hose adapter for a tire inflator, not a compressor or pressure gauge. The official page describes a 90-degree push-to-lock chuck, a 19.96-inch hose, a 0.305-inch × 32 TPI connection and a 200 PSI maximum working pressure. Fanttik says it works with all of its tire inflators and most cordless inflators, but that broad wording does not confirm every third-party connector. The exact US Default Title variant, SKU USAWEBFTKN1098859, was listed at $17.99 on October 24, 2026. No model-specific code appeared on the page, so this review makes no discount or after-code price claim.

What stands out
- The 19.96-inch extension and 90-degree chuck can give more room to connect at a valve than a short, straight fitting
- Fanttik publishes the connector thread and maximum working pressure, giving buyers concrete details to compare with a pump
- Fanttik lists compatibility with its tire inflators, so existing owners can check the exact connection before ordering
Before you buy
- This is a hose adapter only; it does not inflate a tire, measure pressure or increase a compressor’s output
- The phrase “most cordless inflators” is broad. Confirm thread and coupling fit on a third-party pump before buying
- The 200 PSI figure is the listed hose limit, not a tire target. Use the vehicle’s specified cold pressure and stay within every connected component’s limit
- At 19.96 inches, the extra hose needs a place to coil and store
- The page listed $17.99 and showed no LH04-specific code on October 24, 2026
What the LH04 changes
The LH04 adds hose reach and a 90-degree push-to-lock chuck to an existing tire-inflation setup. Fanttik lists the hose at 19.96 inches and describes the chuck as a quick way to attach to a tire valve. It remains an adapter: the pump supplies the air, and a separate suitable gauge or the inflator’s supported display is needed to confirm the tire pressure.
Check the connector before relying on compatibility
Fanttik lists a 0.305-inch × 32 TPI US fine-thread connection and says the LH04 works with all Fanttik tire inflators and most cordless inflators. The page does not provide a model-by-model list for third-party pumps. Before ordering, compare the LH04 connection with the exact pump outlet, then check the pressure limit for the pump, hose and chuck as a system.
Keep the hose limit separate from the vehicle target
Fanttik lists a maximum working pressure of 200 PSI and a maximum temperature of 212°F. Those figures describe the adapter’s stated limits; they do not tell a driver what pressure to use in a car tire. Use the vehicle’s door placard or owner’s manual for the cold-tire target, and check the result with an appropriate gauge. Do not exceed the limit of any connected part.
The listing price has no LH04 code attached
On October 24, 2026, Fanttik’s US product page listed Default Title variant 49908565278963, SKU USAWEBFTKN1098859, at $17.99 USD. This is a dated listed price, not a code result or a promise of future pricing.
Who should choose the LH04
The adapter can suit a driver whose compatible pump already works for their tires but whose hose or chuck angle makes valve access awkward. It is a poor match if you need a compressor, a pressure gauge, a confirmed universal fitting or a documented match to a third-party pump that Fanttik does not identify.
A good fit for
Drivers who already own a compatible tire inflator and want extra hose reach with a 90-degree lock-on chuck. Fanttik listed the exact US variant at $17.99 on October 24, 2026; no LH04-specific code was shown.
Consider another option if
Drivers who need an inflator or pressure gauge, cannot confirm the pump connection, or expect a universal fitting to work without checking the exact model.

Will it fit every cordless inflator?
Fanttik says it works with most cordless inflators and all Fanttik tire inflators, but does not publish a third-party model list. Check the exact pump connection and pressure rating before ordering.
Is 200 PSI the pressure I should use in my tires?
No. That is Fanttik’s maximum working pressure for the adapter, not the vehicle’s recommended tire pressure. Use the cold pressure on the vehicle placard or in its manual.
Does the LH04 check tire pressure?
The LH04 is an extension hose and chuck. It is not a pressure gauge; use a suitable gauge or a compatible inflator’s documented pressure display to verify the result.
