If you maintain a line shaft conveyor, the coupling between sprockets can turn into a daily frustration. Steel chain couplers bring grease, loose pins, and a pile of small parts that seem to vanish at the worst moment. The Delrin Coupler Plastic Sprocket Coupling Chain for Line Shaft Conveyor - Qty 2 is a plastic answer to that problem, and this guide looks at what it offers.
Quick verdict
This two-pack is designed for conveyor setups that use the common 4016 sprocket. At USD 69.71, you get two Delrin couplers with lock pins, ready to wrap around aligned sprocket teeth and secure with a pin. If you want a cleaner, simpler coupling job, this is worth considering.
Who it suits
This coupler suits maintenance teams working on line shaft conveyors with 4016 sprockets. It's also a good fit for shops that want to reduce the grease mess that comes with steel chain couplers. The two-pack size is handy for a single conveyor junction, especially if you're replacing a worn coupling during routine maintenance.
What stands out from the listed details
The Delrin material is the big differentiator. Instead of a greasy steel chain, you're working with a plastic coupler that wraps around the sprocket teeth. Installation involves aligning the sprockets, wrapping the coupler into place, and pressing the locking pin through the hole. There's no need to handle small steel parts or apply lubrication. The pack is made in the United States, and the design is tied to the 4016 sprocket size.
Meaningful trade-offs
The main trade-off is quantity: this listing includes exactly two couplers. If your conveyor has multiple sprocket junctions, you'll need to purchase additional packs. The installation process also demands careful sprocket alignment. If the sprockets aren't lined up, the coupler won't wrap smoothly and the pin won't seat properly. That's a small but important detail to keep in mind.
Bottom line
For $69.71, the Delrin Coupler two-pack offers a focused solution for sprocket coupling on line shaft conveyors. It won't replace every coupling method, but for 4016 sprockets, it gives you a cleaner, easier-to-install option than traditional steel chain.
Delrin Coupler Plastic Sprocket Coupling Chain for Line Shaft Conveyor - Qty 2

This is the product at the center of this review. The pack lists for USD 69.71 and includes two couplers with locking pins. Its main appeal is the pin-based wrap design that skips the grease and small parts of steel chain couplers. The limitation is that you only get two couplers, and installation depends on precise sprocket alignment to get the pin through cleanly. Choose this when you want a lower-maintenance coupling for a 4016 sprocket line shaft conveyor.
