WMFG Kiteboard Pump 4.0T

The WMFG Kiteboard Pump 4.0T is a fourth-generation manual inflation pump built for kites, wings, and SUPs. WMFG, a brand focused exclusively on watersports inflation tools and traction products, designed the 4.0T as an extra-tall, high-volume pump aimed at reducing the time and effort needed to get gear inflated on the beach. The "T" in the model name stands for "Tall," distinguishing it from the shorter 4.0R travel variant in the same product generation.

The pump uses a single-to-double-stroke inflation lever that lets riders switch between high-volume, low-pressure output for initial inflation and low-volume, high-pressure output for topping off. This dual-mode system means one pump handles both the bulk fill and the final pressurization without swapping equipment or adapters mid-session.

• Height: 24" / 61 cm
• Diameter: 4" / 10 cm
• Capacity: 2.9 L per stroke
• Max recommended pressure: 13 PSI
• Included accessories: Kite tether and hook, kite-tuned pressure gauge with integrated sand filter, high-flow hose with threaded fitting, SUP nozzle, multi-brand nozzle adapter kit

The 4.0T is geared toward kiteboarders and wing foilers who want a reliable manual pump that inflates quickly without the cost or charging logistics of an electric unit. Its 24-inch height suits riders who prefer a more upright pumping stance, reducing back strain compared to shorter pumps — a practical consideration for anyone inflating multiple kites or wings in a single session.

The included adapter kit covers a wide range of valve types across kite and wing brands, so riders switching between gear from different manufacturers can use one pump for everything. The 13 PSI ceiling is adequate for standard kite and wing bladders but falls short of what hardshell SUPs or high-pressure inflatables require, so this is not a crossover tool for those applications.

Within WMFG's current pump range, the 4.0T sits in the middle. Below it is the 4.0R, a 20-inch standard-height version of the same generation designed for travel and compact storage, priced lower at around $55. Above it is the 1.0P, a double-barrel pro pump capable of exceeding 25 PSI with a three-stage switch, aimed at riders who need higher pressures or pump across a wider variety of inflatables. At the top of the lineup is the 1.0E, WMFG's electric pump at $229, which removes manual effort entirely.

Compared to generic kite pumps bundled with new kites, the 4.0T offers a larger cylinder diameter, higher per-stroke volume, and a built-in pressure gauge — upgrades that matter most to riders who inflate frequently or own multiple kites and wings. For buyers who want manual simplicity without sacrificing ergonomics or inflation speed, the 4.0T fills the gap between budget pumps and premium electric or pro-level options.
