Quick answer

Replace the spring-loaded bolt (bulón) on your Duromatic pressure cooker lid handle using a genuine Kuhn Rikon replacement part. The process takes about 10 minutes and restores a secure, consistent lid seal.

Why the bolt matters

The spring-loaded bolt on your Duromatic pressure cooker lid handle holds the lid closed during cooking. Over time, the spring can weaken or the pin can wear, causing the handle to feel loose or fail to lock properly. Replacing just the bolt is faster and cheaper than replacing the entire handle.

Genuine vs. generic parts

Kuhn Rikon designs each bolt with precise spring tension and pin dimensions. A non‑genuine part may not fit correctly or may fail under pressure. Using a genuine Swiss‑made replacement ensures your cooker performs as intended and maintains its safety certifications.

Step-by-step replacement

  1. 1. Remove the old bolt: Turn the Duromatic lid over so the handle faces up. Use a small flat‑head screwdriver or a coin to press the spring tab on the underside of the handle. Slide the old bolt out of its slot. If the spring tab does not move freely, apply a drop of penetrating oil and wait 5 minutes before trying again.
  2. 2. Insert the new bolt: Take the new Kuhn Rikon replacement bolt (bulón) and align the colored spring with the slot in the handle. Push the bolt in until the spring tab clicks into place. You should hear and feel a positive lock. Do not force the bolt. If it does not slide in easily, check that you have the correct orientation — the spring should face downward toward the lid.
  3. 3. Test the lid lock: Close the lid on the pressure cooker base without any liquid inside. Rotate the handle to the locked position. The lid should not lift off when you tug gently. Rotate to unlock and confirm smooth operation. If the lid still feels loose, remove the bolt and reinsert it, making sure the spring is fully seated. A bolt that is not fully locked will not hold pressure.
