UltraZap Bio Filter Lid & O-Ring Replacement Seal

Keep Your Pond Filter Secure & Leak-Free

Is your UltraZap Bio Filter lid damaged, cracked or no longer sealing properly? The UltraZap Bio Filter Lid & O-Ring Replacement Seal is a simple way to replace worn or damaged components without having to purchase an entirely new pond filter.

Designed for compatible UltraZap Bio Filters, this replacement set includes a lid and matching O-ring seal to help keep your filtration system securely closed.

The O-ring fits between the filter lid and body, creating a watertight seal that helps prevent leaks during normal operation.

Whether you're maintaining a koi pond, garden pond or fish pond, replacing worn filter parts helps keep your existing filtration system working as it should.

Why You'll Love It

  • Secure, Watertight Seal: Helps prevent unwanted leaks around the filter lid.

  • Lid & O-Ring Included: Everything you need to replace these two components.

  • Designed for UltraZap Bio Filters: Suitable for compatible UltraZap filtration systems.

  • Cost-Effective Repair: Replace damaged parts instead of purchasing a complete new filter.

  • Helps Maintain Filter Performance: Keeps the filter securely closed during operation.

  • Easy Replacement: A convenient solution for routine pond filter maintenance.

  • Available in Multiple Sizes: Suitable for UltraZap Bio Filters ranging from 5 to 50 litres.

  • Ideal for Pond Maintenance: Perfect for maintaining existing koi, fish and garden pond filtration systems.

What's Included?

Each replacement set contains:

  • 1 × UltraZap Bio Filter Replacement Lid

  • 1 × Matching O-Ring Seal

Please note: This listing includes the replacement lid and O-ring only. The complete UltraZap Bio Filter is not included.

Compatible UltraZap Bio Filter Sizes

The replacement lid and O-ring set is available for the following UltraZap Bio Filter models:

  • 5 Litre Bio Filter

  • 10 Litre Bio Filter

  • 15 Litre Bio Filter

  • 25 Litre Bio Filter

  • 50 Litre Bio Filter

Please select the correct size to match your existing UltraZap Bio Filter before placing your order.

Why Is the O-Ring Important?

The O-ring plays an important role in keeping your pond filter properly sealed.

It sits between the filter lid and filter body, helping prevent water from escaping through the connection.

Over time, O-rings can become worn, flattened, cracked or damaged. This may cause water to leak around the lid, even when the lid is securely fitted.

Replacing a worn O-ring can help restore the seal and keep your filtration system operating properly.

When Should You Replace Your Filter Lid or O-Ring?

It may be time for a replacement if:

  • Water is leaking around the filter lid.

  • The existing lid is cracked or damaged.

  • The O-ring has become brittle, flattened or stretched.

  • The seal no longer fits securely.

  • The lid is missing or no longer closes properly.

  • You're carrying out maintenance on your existing UltraZap Bio Filter.

Replacing these components when necessary can help extend the useful life of your filtration system.

Ideal Applications

The UltraZap Bio Filter Lid & O-Ring Replacement Seal is suitable for compatible filtration systems used in:

  • Koi Ponds: Maintain a secure seal on your existing pond filter.

  • Garden Ponds: Replace worn filtration components.

  • Fish Ponds: Help keep your filtration system operating effectively.

  • Ornamental Ponds: Maintain compatible pond filtration equipment.

  • Water Features: Suitable for installations using compatible UltraZap Bio Filters.
