Many riders struggle when mounting hoses to one pump valves. The plastic collet often feels tight and the job stops halfway. A simple method reduces effort and locks the hose in a safe position.

One pump systems use three main parts. The one pump hose. The clips to prevent airflow. The plastic collet that locks the hose to the valve.

With practice you'll need less than 20sec to do one ;).

Step by step mounting instructions for the plastic collet

S1. Slide the collet onto the hose

Place the collet on the hose first. The open side faces the hose end. Push the collet a few centimetres back so there is free hose at the tip for mounting on the valve.

S2. Push the hose onto the valve

Press the hose end straight onto the valve fitting. Use both hands and push until the hose sits at the stop on the valve. A straight push keeps the hose wall even and protects it from damage.

S3. Lock the collet in place

Slide the collet toward the valve. While you push the collet forward, pull the hose slightly in the opposite direction. This stretch makes the hose a little thinner on the valve nipple. The collet then moves into place with less force. Push until the collet sits fully against the valve base.

S4. Repeat on the second valve

Use the same order on the other end of the hose. Collet on hose. Hose on valve. Collet locked while the hose is pulled back. Do not forget of putting back / to mount clips if you're exchanging hoses prior locking hose to the second valve.

Durability notes

New Dr.Tuba hoses tolerate stronger pulling during this procedure. This tension helps the collet find its seat and does not harm the hose wall. All our hoses are made locally from high quality silicone tubing, which is pre-talced from inside / outside for easier installation.

Old hoses that come with many kites and wings often have UV damage and small cracks. Material like this tears much faster. Reduce force, inspect for lines and splits, and replace hose sections that look tired.

The video walks you through the whole procedure in real time. The clip shows the full mounting sequence, collet on the hose, hose pushed onto the valve, then the collet locked while the hose is pulled back.Follow the same order every time and one pump connections stay firm, clean and easy to service.

Frequently Asked Questions

Why does mounting the collet often feel difficult?

In many cases the collet is pushed without any pull on the hose. The hose then stays thick on the valve nipple and the collet jams halfway due to tight locking radiuses needed to prevent airflow or to hold internal pressure (eg. tubing not failing off the valve.)

Is heating of the hose needed for installation?

No. When the collet goes on first, then the hose onto the valve, then the collet forward while the hose is pulled back, extra heat is not required.

Does pulling the hose cause damage?

New Dr.Tuba hoses tolerate strong pulling during installation. Old or sun aged hoses often have brittle sections that tear under the same load, so they need more gentle handling and frequent inspection. And it's just better to exchange them since they will started to leak air.

How do I know the collet is fully seated?

The collet sits tight against the valve neck base. The hose feels locked and no longer slides off by hand.

Does this mounting method work across brands?

Most one pump systems in kites and wings follow the same design. The sequence described here gives a secure connection on a wide range of brands. The differences are only with locking mechanism used - we focused here on collets only. Click clips does not need pulling, just mounting the hose on the valve.

Collets vs. Click-Clips?

Both of them do their job when installed correctly. However collets does not need any mounting tooling, while click clips in most cases do need pliers to lock them together.
