 Product Description

A7 Rib inflation valve.

Rib valve fitted to early Avon, Ribtec and Humber Ribs.

The A7 Rib inflation valve has been fitted to may older Ribs and inflatables including Avon, Ribtec, Ribcraft, Delta and Humber.

Before you replace the A7 valve, it might be worth checking that the nut that holds the valve in position is not loose and that is not where the boat is losing air.  If this is where the A7 valve is losing air then try tightening the nut to 20Nm.

Test the centre of the valve using soapy water and if the air is leaking from this area then replace the valve service kit, click here.

To install the A7 valve repair / spares kit:  

1. Push in the valve spindle and twist to the left to lock the valve open.

2. Completely deflate the Rib tube.

3. Undo and remove the nut and washer

4. Keep the tube flat and close to the ground as it can be difficult to recover the valve if it falls into the tube.

5. Push the valve in through the hole making sure you keep hold of the valve and rotate it until you can see the diaphragm.

6. Get hold of the seal with pliers being careful not to damage the valve body and break the diaphragm away from the spindle.

7. Rotate the valve back to its original position, turn the spindle to the right, and remove the spindle and spring

8. Fit the new spring and spindle into the valve body. Push in and rotate the spindle to the left to lock it in the open position.

9. Rotate the valve back around until you can see the thread of the spindle.

10. Screw the new diaphragm onto the spindle. Tighten so its finger tight.

11. Rotate the valve back around and push it back through the fabric hole.

12. Refit the washers and nut in the same order.
