Rubber Seal For Pressure Cooker 18 cm — Reliable Replacement Seal for Your Pressure Cooker

1. Description

When you’re using a pressure cooker, the integrity of the seal is absolutely critical to safe and effective cooking. The Rubber Seal For Pressure Cooker 18 cm is designed specifically to replace worn-out or damaged gaskets for pressure cookers with a lid diameter around 18 cm. This sealing ring ensures that your cooker maintains proper pressure, prevents steam leakage, and allows you to cook efficiently, safely and reliably.

Crafted from high-quality rubber or silicone (depending on the model), the gasket fits snugly into the groove under the lid of your pressure cooker. Over time, gaskets can become hard, brittle, deformed, stained or odorous — significantly reducing cooking performance and safety. Replacing the seal restores full pressure functionality, improves heat retention, and helps maintain the longevity of your cooker.

This replacement seal is compatible with many pressure cooker brands that have an 18 cm diameter lid. It’s a smart accessory for Kiwi kitchens — especially since replacing the seal is far more economical than replacing the entire cooker, and it helps you maintain safe cooking conditions when preparing hearty meals.

The rubber seal is constructed to withstand high temperatures and steam conditions typical of pressure cooking. It’s easy to install: remove the old gasket from the lid, clean the groove, fit the new seal evenly all around, check it’s seated properly, then proceed with your cooking with confidence.

In summary: this is not just a spare part — it’s a kitchen safety essential, helping you keep your pressure cooker performing at its best for soups, stews, beans, roasts and one-pot meals.

3. Benefits

Restores Cooking Efficiency

When your pressure cooker’s gasket is worn out, you’ll likely notice longer cooking times, steam escaping, or the lid failing to maintain full pressure. By replacing it with a new rubber seal, you restore the cooker’s ability to build and maintain internal pressure — meaning faster, more efficient cooking and better results.

Improves Safety

A proper seal is critical for safe pressure cooking. If the gasket fails, steam may escape or pressure may not build correctly, increasing risk of under-cooked food or unsafe lid behaviour. A fresh replacement ensures that your cooker operates reliably within its designed safety parameters.

Prolongs Cooker Life

Rather than retiring your pressure cooker because of a worn seal, replacing the gasket helps you extend the life of your existing appliance. The magic is in maintenance: a new rubber seal means your unit can continue performing as though it were near-new.

Cost-Effective

For Kiwi households, keeping cooking costs down is always a plus. Rather than investing in a whole new cooker, exchanging a gasket is a relatively low-cost fix that delivers big performance improvements.

Better Cooking Results

With a full seal, your pressure cooker can trap steam and heat, which ensures even cooking of beans, lentils, meat, pulses, soups — preserving texture and nutrients. You’ll get consistent results and enjoy one-pot meals the way they were meant to be.

Minimal Effort for Installation

You don’t need special tools or expertise: installation is straightforward. That means less downtime and fewer frustrations — especially useful when you’re in the middle of meal-prep.

Peace of Mind

Knowing you’ve replaced a critical component gives you confidence that your pressure cooker is safe, reliable and ready for whatever cooking challenge you’ve got.

Eco-Friendly

By extending the life of your appliance rather than discarding it, you reduce waste and make a more sustainable choice — aligned with Kiwi values of resourcefulness and care for the environment.
