APEX R.I.V. Rapid Inflation Valve STD - single
A single APEX R.I.V. fast inflation valve in STD length — to complete a set, to arm the spare wheel or to replace a damaged one. It fits dual valve-stem wheels only, and the valve counterbore in your wheel decides between the STD and the XL length, so measure it before ordering. The manufacturer does not include the R.I.V. chuck with a single valve.
APEX R.I.V. Rapid Inflation Valve STD - single
Airing up after a trail is usually the longest part of the day, and one wheel left on a factory stem spoils the whole effect — that is the wheel you stand at longest.
The R.I.V. goes after the cause: a valve that does not throttle the air, so the compressor delivers what it really has.
SET 1 valve, STD length | INFLATION TIME Under 10 s at 120 PSI and 10 CFM | REQUIREMENT Dual valve-stem wheels |
Key benefits
- With the regulator set the compressor shuts off by itself at the target pressure; inflation time rises by 10-20%, but you are not standing over the wheel with a gauge.
- On an on-board system a hose with 0.188 inch inside diameter is enough; on shop air the minimum is 0.250 inch.
What is in the kit
- 1 x APEX R.I.V. valve in STD length
Technical data
- Manufacturer part number: X02-02-013
- Intended for: dual valve-stem wheels only
- Connection thread: female 1/4-18 NPT
- Pressure drop across the valve: negligible — the compressor has an easier time, runs cooler and lasts longer
- Inflation time: under 10 seconds per 37-39" tyre on a 120 PSI, 10 CFM shop compressor; on on-board air it depends on compressor output and pressure
- Status: patent pending
Who it is for
This is the one to buy to complete a set: you already run R.I.V. valves on the road wheels and need a fifth for the spare, or you are replacing one after damage.
Installation: measuring, torque and hose
Measuring the counterbore. Measure the valve counterbore in your wheel before you order. The STD version fits where the counterbore is 0.500 inch or less, or 0.600 inch with the seal flipped. Above that the XL version is the right one, with a limit of 0.900 inch.
Torque. Tighten the valve to 18 in-lbs on a 14 mm hex. The cap goes on finger tight only — no spanner on the cap.
Hose. You connect the R.I.V. chuck to a hose with a hose barb sized to your hose — the manufacturer does not include one, and 1/4 and 3/8 are the common sizes.
Fit and care. AEV wheels with their particular style of valve protector are ruled out by the manufacturer. The manufacturer also prohibits cleaning with acids. If the check valve starts to weep, wiggle it in and out several times with a small Allen wrench to clear the dirt.
Frequently asked questions
Is the single valve the same version as the ones in the sets?
Yes — it is a valve in STD length, like the ones in the four and five valve sets.
Do I need the R.I.V. chuck for it?
Yes, if you do not have one yet. R.I.V. valves are served only by the separate R.I.V. Screw On Air Chuck, which is not compatible with standard Schrader valves — the manufacturer supplies it with the four and five valve sets only.
Is this the same valve as the RPV?
No. The R.I.V. is for fast inflation, the RPV for fast deflation — two separate products.
