Servicing a Titan Industrial TG6500D or TG7500D diesel generator often means choosing between two replacement parts that share the same model compatibility: a complete repair gasket set and a single alloy piston. They're both new, both carry a warranty, and they're priced only a dollar apart. But they serve very different repairs. Here's how to decide which one actually belongs on your workbench.
Quick Verdict
If your goal is to stop leaks and reseal the engine after a top-end job, the Repair Gasket Kit Type A is the obvious pick: it bundles the cylinder head, valve cover, manifold, and other gaskets into one purchase. If you're replacing a damaged piston, the Alloy Piston Type B is the intended part, but it requires a separate ring set and a compatibility check: the piston's description cautions it does not fit engines that use a 3-hole valve cover gasket. The gasket kit includes that 3-hole gasket, so make sure you know your engine's head cover style before ordering.
Price & Included Parts
| Feature | Repair Gasket Kit Type A | Alloy Piston Type B |
|---|---|---|
| Listed price | USD 36.99 | USD 35.99 |
| Brand | EZP | EZP |
| Condition | New | New |
| Warranty | Yes | Yes |
| Part No. | EZ-TITAN/TG7500D-CRGK-A | EZ-TITAN/TG7500D-PISTON-TB |
| Included components | Full gasket set with cylinder head, valve cover, manifold, and more | One aluminum alloy piston (ring set not included) |
Which Part Should You Buy?
Beyond the $1 price difference, the real differentiator is what's in the box and which engine version you have. The gasket kit is a multi-piece sealing set: crankcase cover gasket, cylinder head gasket, 3-hole valve cover gasket, oval-shaped gasket, nozzle gasket, air intake manifold gasket, air cleaner gasket, fuel pump shim and sealing gasket, oil drain plug gasket, muffler gasket, and a fuel injector copper washer. That's a comprehensive set for a reseal.
The piston is a single high-strength aluminum alloy piston for the same generator series. It's described as premium Type B, and explicitly notes the piston ring set is not included and is sold separately. Most importantly, the caution states the piston does not fit if your OEM cylinder head cover uses two long mounting bolts and a valve cover gasket with three holes. That's the biggest compatibility checkpoint in this comparison.
Product Notes
Titan Industrial TG6500D TG7500D Diesel generator Repair Gasket Kit Set Type A

This Type A gasket set from EZP is built around a full reseal: you get crankcase cover, cylinder head, 3-hole valve cover, oval, nozzle, air intake manifold, air cleaner, fuel pump shim, fuel pump sealing gasket, oil drain plug gasket, muffler gasket, and fuel injector copper washer. It's a new part with a yes warranty and part number EZ-TITAN/TG7500D-CRGK-A. The listed price is $36.99. The main limitation is that the 3-hole valve cover gasket ties it to the head cover style that the piston listing explicitly says is incompatible with the Type B piston. Before you order, confirm your generator uses that gasket style, because a different head cover would need a different gasket kit.
Titan Industrial TG6500D TG7500D 6.5 7.5KW Diesel Generator Alloy Piston Type B

This Type B piston is a single high-strength aluminum alloy replacement for the TG6500D/TG7500D series, listed at $35.99. It's new, carries warranty yes, and uses part number EZ-TITAN/TG7500D-PISTON-TB. The description stresses that the piston ring set is not included and is sold separately, so factor that into your rebuild budget. It also carries a specific compatibility caution: if your cylinder head cover uses two long mounting bolts and a 3-hole valve cover gasket, this piston does not fit. That makes the part a solid choice for the other engine variant, but you'll need to verify your head cover before purchasing.
Final Choice by Use Case
If you're doing a top-end gasket refresh, the Repair Gasket Kit Type A gives you the sealing components in one box. If you're replacing a piston and your engine doesn't use the 3-hole valve cover gasket style, the Alloy Piston Type B is the part to order. With only a $1 spread between the two, the decision isn't about price - it's about matching the part to the specific repair and the head cover configuration on your Titan Industrial generator.
