Quick Take
All four listings are marked new, so the real decision is which size and design fits your sink. At a glance, the two under-sink interceptors are the lower-priced picks, while the PE plastic trap lands in the middle and the AOKNV separator anchors the high end. Your main choice is whether a compact unit is enough or you need the larger processing capacity.

Product Notes
Commercial Grease Trap, Lightweight PE Plastic Grease Interceptor Trap Side Inle
The main draw here is the lightweight plastic construction. The listing shows a 13-inch by 13-inch by 6-inch unit, a 6.6-pound weight, and an included oil sump, so this is the model to consider if you want a compact side-inlet design without a stainless-steel body. It is not the lowest-priced route: at USD 142.49, it sits clearly above the two stainless models. The limitation is that the listed details focus on dimensions and weight rather than capacity in liters or gallons, so this choice makes more sense for a space-conscious setup than for a high-volume drain.
Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US
At USD 49.02, this is the entry point for a stainless steel under-sink interceptor. It lists an 18-20L capacity, 35cm x 25cm x 23cm overall dimensions, and 4.8cm wastewater inlet and outlet diameters. The included parts are the grease trap, drainage pipe, and lid. This is a good fit if you need a moderately sized unit at a low listed price. The obvious limit is capacity: 18-20L is fine for a moderate sink load, but not for heavier wastewater.
40lbs Grease Trap 15.32 GPM Water Oil-water Separator Commercial Interceptor
This AOKNV separator is the heavier-duty option in the group, with a 40 lb capacity and a 15.32 GPM flow rate. The listing describes a dual-tank design that separates grease, water, and solid food residue at once, and the threaded connection plus 30in drainage pipeline distinguish it from the under-sink models. It is also the highest-priced product here at USD 180.20, so the reason to choose it is processing capacity rather than price. If your sink drains handle only modest amounts of oil and food waste, the stainless under-sink units cover the job with a lower listed price.
Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US
This second stainless listing is nearly identical to the USD 49.02 version, coming in one cent higher at USD 49.03. It repeats the capacity, material, and dimensions of the other stainless unit, while its listed highlights emphasize easy installation, convenient use, and easy operation. The reason to pay attention to it is the same: a compact stainless interceptor for the same style of sink. The limitation is that it does not add any capacity or connection difference compared with the other stainless unit, so the practical choice between the two comes down to the one-cent listed price and the exact wording you prefer.
Final Recommendation by Use Case
For a standard under-sink draining setup, one of the two stainless interceptors is the straightforward pick: it gives you a compact size at the lower end of the group's listed price spread. If you need more capacity and a built-in flow rate for heavier wastewater, the AOKNV separator is the one to choose despite the higher listed price. If you'd rather avoid stainless, the PE plastic grease trap is the middle-ground option.
