ABTER 7-Fin 4" Male Blade Replacement with 24oz Blender Cup — Nutri Ninja-Style Fit, Corrosion-Resistant

ABTER's replacement 4-inch, 7-finned male blade assembly paired with a 24oz blender cup restores heavy-duty chopping and blending performance for compatible Nutri Ninja-style machines.

When a blender's blade wears, corrodes, or leaks, swapping in a robust replacement is an easy way to get reliable results without buying a new base unit. This ABTER kit includes a redesigned 4-inch male 7-fin stainless blade engineered to match the performance profile of larger Nutri Ninja-style pitchers and the accompanying 24oz cup sized for single-serve smoothies, sauces, and prep tasks.

How do I know this blade fits my blender?

Measure the diameter of the machine's blade housing and compare it to a standard credit card laid across the opening; the 4-inch blade matches housings roughly the width of a credit card. This model is specifically a male 7-fins blade intended for larger cups—not the smaller 3.35-inch assemblies or female-style blades.

• Compatible with Nutri Ninja-style bases that accept 4-inch male blade assemblies.
• Not compatible with 16oz cups or units built for 3.35-inch blades (check your model).
• Not for use with machines that require female blades or 6-fin rotors.
• Compare circumference to a credit card for a quick fit check.

What improvements does this ABTER blade offer compared to older replacements?

The blade design was reengineered to reduce common failures like cracking, leaking seals, and surface rust. It uses corrosion-resistant materials, improved sealing, and construction intended for frequent dishwasher cleaning, giving longer service life under regular use.

• Seven-fin blade geometry for efficient chopping and smoother purees.
• Upgraded sealing to minimize leaks over time.
• BPA-free materials and dishwasher-safe components for easy cleanup.
• Quality-tested to resist rust and deterioration under normal kitchen use.

Which blender models or cup sizes should I avoid with this kit?

This kit is not universal: avoid it if your system uses a 3.35-inch blade, a female-style connector, or a six-fin rotor. It also does not fit Ninja SS series models or many 16oz-capacity cups designed for smaller blades.

• Not for 16oz cups or blenders that accept 3.35-inch blades (several compact models).
• Not compatible with 6-fin blades or female-blade style systems.
• Not suitable for many Ninja SS series and similarly designed bases (check model list before purchase).
• If unsure, compare your existing blade assembly to product photos and measurements.

How should I care for the blade and cup to extend their life?

Rinse soon after use and remove thick residues before washing to keep seals and sharpening intact. Both parts are dishwasher-safe, but handwashing and drying can further reduce wear and preserve the finish and gasket condition.

• Rinse immediately after use to prevent food buildup around the seal.
• Dishwasher-safe, but handwash for longest gasket life and blade finish.
• Inspect gaskets and threads periodically for wear; replace if leaking develops.
• Store disassembled and dry to prevent trapped moisture and corrosion.

Who is this for? This ABTER replacement blade and 24oz cup kit is aimed at home cooks and smoothie lovers who own Nutri Ninja-style bases that accept a 4-inch male 7-fin blade and want a durable, affordable replacement. It's best for people who prepare single-serve smoothies, purees, and prep tasks with larger-capacity cups and who value improved sealing, rust resistance, and easy cleaning. If your machine uses a smaller 3.35-inch blade, a female connector, or a 6-fin assembly, choose the model that matches those specifications instead.
