Choosing between two seal kits sounds simple, but the wrong one sends you back to hunting for parts. One set is a gray blender gasket for Hamilton Beach jar bases, and the other is a pair of white urethane o-rings for piercing caps and valves on QB78-style air rifles. They're not interchangeable, so the decision really depends on which equipment you're repairing.
Quick Verdict
If your blender jar leaks at the cutter base, pick the Hamilton Beach 2 Pack Blender Replacement Rubber Plastic Gasket Ring Seals at USD 6.99. It comes with two gaskets sized for Hamilton Beach domestic blenders and commercial models 908/909. If you're working on a QB78, QB78 Deluxe, TH78, XS78, or another "78"-based air rifle, go with the QB78, QB78D, XS78,TH78 Piercing Cap & Valve TWO (2) O-Ring Seals URETHANE at USD 5.75. It's a two-pack of factory-style urethane seals for the piercing cap and valve, and the listed price difference is $1.24.

Where Each Product Wins
- For blender repairs: The Hamilton Beach set is the one to grab. It's a Felji-branded replacement gasket kit for Hamilton Beach domestic blenders and commercial models 908/909, and you get two gaskets in the pack.
- For air rifle maintenance: The QB78/TH78 o-ring set is the right fit. It's specifically listed for QB78, QB78 Deluxe, TH78, XS78, and other "78"-based models with a piercing tube cap, and the urethane material is described as offering superior strength, tear, and abrasion resistance.
- For the lower listed price: The o-ring kit is listed at $5.75 compared with $6.99 for the blender gasket set. Keep in mind these are different parts for different machines, so price probably won't drive the choice by itself.
Product Notes
Hamilton Beach 2 Pack Blender Replacement Rubber Plastic Gasket Ring Seals
This kit holds two gaskets, flat o-ring washers that sit between the cutter and the jar. It's a Felji replacement part for Hamilton Beach domestic blenders plus commercial models 908 and 909, in gray. If the part number isn't obvious, the 1.875-inch inside diameter and 2.68-inch outside diameter give solid measurements to compare against your current gasket. The reason to choose it is straightforward: it's a two-pack for a common blender make, so you'll have a spare. The limitation is the scope: it's made for Hamilton Beach blenders, so if your appliance is another brand, this flat gasket isn't the right replacement for that setup.
QB78, QB78D, XS78,TH78 Piercing Cap & Valve TWO (2) O-Ring Seals URETHANE
This pair is for the piercing cap or valve area of QB78, QB78 Deluxe, TH78, and XS78 air rifles, plus variants and calibers built on the "78" platform with a piercing tube cap. The seals are labeled #3401 and #0409; the two seals are identical and interchangeable, even though two part numbers are shown in the owner's manual. Made in the United States from urethane, they're white, and urethane offers superior strength, tear, and abrasion resistance. That makes them a solid pick for maintaining piercing components. The limitation is the scope: these are specific to the "78" family's piercing cap and valve arrangement, not generic o-rings for every airgun. If your gun doesn't use this cap design, this set isn't intended for it.
Final Choice by Use Case
- Have a Hamilton Beach blender leaking around the cutter base? Choose the Hamilton Beach 2 Pack Blender Replacement Rubber Plastic Gasket Ring Seals at USD 6.99. The two included gaskets and the listed dimensions give you a clear replacement path.
- Own a QB78, QB78D, XS78, or TH78 air rifle and need piercing cap or valve seals? Choose the QB78, QB78D, XS78,TH78 Piercing Cap & Valve TWO (2) O-Ring Seals URETHANE at USD 5.75. The two-pack of urethane seals is built for that specific component.
