Case Study: Real Business, Real Results

The Rutland Deli in Oakham needed to ensure their signature line of homemade preserves was perfectly sealed for sale, as their old gaskets were becoming brittle and  causing occasional spoilage.

"We simply can't afford to lose a single jar of our best-selling rhubarb and  ginger jam. These replacement canning gaskets fit our Weck jars perfectly and  give us complete confidence that every seal is 100% secure. Our reputation is built on quality, and  this helps us deliver it."

Robert Davies – Proprietor

The deli completely eliminated spoilage from failed seals and  reported a 15% faster jarring process due to the easy-fit nature of the new washers.

Installation and  Maintenance Guide

Setting It Up

  • Always start with a spotlessly clean and  completely dry jar rim and  lid.
  • Gently stretch the new rubber washer over the glass lid until it sits snugly.
  • Double-check that the seal is lying flat and  evenly all the way around the groove.
  • Place the lid onto the jar and  secure it with the metal clips as you normally would.

Keeping It Going

  • After use, wash the seal by hand in warm, soapy water.
  • Avoid using a dishwasher, harsh chemicals, or abrasive pads as they can degrade the rubber.
  • Before each use, give it a quick once-over for any cracks or brittleness and  replace if it looks worn.
  • Store your spare seals flat and  away from direct sunlight or heat to keep them in top condition.

Buying Guide: Choosing the Right Jar Seals

Not sure what fits best? Here’s a quick guide to getting the perfect seal for your needs.

Check Your Size & Model

Seals aren't one-size-fits-all. Always match the seal to your specific jar model—these are for GH390 jars—to guarantee a perfect, leak-proof fit.

Material Matters

Natural rubber, like in these seals, offers fantastic flexibility and  a traditional, reliable seal for classic water-bath canning and  storage.

Know When to Replace

If a seal becomes hard, brittle, cracked, or permanently stained, it's time for a new one. A fresh seal is the cheapest insurance for your valuable produce.

Intended Use

These seals are ideal for preserving, pickling, and  dry storage. For high-pressure or high-temperature cooking, always check if a different type of seal is required.

Stock Up and  Save

Buying a multi-pack is always a smart move. It's more cost-effective and  ensures you always have a spare ready for your next batch of preserving.

Frequently Asked Questions

Q: Are these Weck jar seals reusable?

A: Yes, they can be carefully washed and  reused multiple times. However, you should always inspect them for any signs of wear, cracks, or brittleness before each use.

Q: How do I know if I've achieved a good seal after canning?

A: After the jar has completely cooled, the lid should be firmly sucked down onto the jar. If the lid is loose or can be lifted off easily, the seal has failed.

Q: What are these replacement canning gaskets made of?

A: These seals are made from a high-quality, food-safe, and  durable natural rubber.

Q: How many seals come in one pack?

A: Each pack contains 10 individual APS GH389 rubber gaskets.

Q: Will this silicone sealing ring for Weck jars fit all models?

A: These are rubber, not silicone, and  are specifically designed to fit the GH390 Weck jar model. Compatibility with other models is not guaranteed.

Q: How should I clean these washers?

A: The best way is to wash them by hand with warm water and  mild soap. Avoid the dishwasher as high heat can cause the rubber to degrade faster.

Q: My seal isn't working. What could be wrong?

A: First, check the jar rim for any nicks or food residue. Then, ensure the seal itself isn't twisted, damaged, or old. A clean surface and  a fresh seal are key.

Q: What colour are the seals?

A: These seals are clear/natural rubber coloured, allowing you to see the contact with the glass for a perfect fit.

Really good quality Weck jar seals. A bit snug to get on the first time, but that's what you want for a tight seal. Very happy with them.

Ben Carter – Farm Shop, Sussex

Brilliant! We use these for storing our loose-leaf teas on the counter. They keep everything wonderfully fresh and  aromatic.

Why a Perfect Airtight Seal is a Must-Have

What exactly does an 'airtight seal' do? Think of it like a security guard for your jar. Its main job is to stop tiny invaders—namely oxygen, moisture, and  airborne bacteria—from getting inside and  ruining the contents. Oxygen is the number one enemy of freshness; it causes food to discolour, lose nutrients, and  eventually spoil. These APS rubber washers create a perfect barrier by pressing firmly between the glass lid and  the rim of the jar. This action forces the air out and  prevents it from getting back in, effectively 'locking in' the freshness, flavour, and  quality, ensuring what you taste weeks later is just as good as the day it was made.

Who Should Buy This?

  • Artisan Cafés & Delis: Perfect for stylishly storing and  selling homemade jams, chutneys, and  pickles with confidence.
  • Farm Shops & Producers: Essential for reliably sealing small-batch preserves, honey, and  sauces for retail sale.
  • Bistros & Restaurants: Ideal for supreme pantry organisation, keeping ingredients like herbs and  spices perfectly fresh.
  • Passionate Home Preservers: A must-have for anyone serious about preserving their garden harvest with professional results.
