Roomtex Valve Mark 31 (new, 1pc)

The new generation of our famous essential valves.

Changes compared to mk. 30:

1. The design has become simpler and more reliable. Instead of double rings, we have returned to a more compact version with a single ring. The valves have become lighter and more convenient.

2. New material — polycarbonate. It is significantly more resistant to impact, chipping, and cracking than acrylic.

3. A larger latex membrane provides higher tightness (99–100%) while maintaining low airflow resistance.

Roomtex valves are designed for convenient inflation of medium and large balloons using either a pump or your mouth. The rim and retaining loop securely hold the balloon on the valve, minimizing local overstretching of the latex and allowing the balloon to reach its maximum size.

Roomtex valves come in three sizes: M (with a rim diameter of 6 cm/2.36''), L (9 cm/3.54''), and XL (14 cm/5.51''). The description of each of our balloons specifies which valve size is suitable for it.

The current version of Roomtex valves is highly airtight, allowing them to be used for short-term sealing of balloons. However, they are still an aid to inflation, so we cannot guarantee absolute airtightness.

Instructions for using the valve are shown in the last photo.

In this batch, different valves may have different mouthpiece lengths-we experimented with different options. The valves are supplied in protective bubble wrap — рlease open carefully so as not to cut the retaining loop or membrane.
