What products do you sell?

We specialize in high-quality aftermarket hydraulic rock breaker seal kits and high-pressure diaphragms. These are precision replacement parts designed for popular brands including Epiroc, Rammer, Atlas Copco, Bobcat, Stanley, Montabert, Furukawa, Kent, and many more.

Are your parts OEM or aftermarket?

All our parts are high-quality aftermarket. They are manufactured to meet or exceed OEM specifications using premium materials (such as HNBR rubber and polyurethane) at a much better value than original parts.

How do I know which seal kit or diaphragm fits my breaker?

The best way is to provide us with your breaker’s brand, model, and serial number. Call 844-2-SEALKIT or use our “Search by Make & Model” tool. Our team has over 20 years of hands-on experience and can verify compatibility quickly and accurately.

What materials are your seal kits and diaphragms made from?

We use premium compounds including:

HNBR – Excellent heat and oil resistance (most popular)

Polyurethane (PU) – Superior abrasion and wear resistance

NBR – Good for standard applications

FKM/Viton – For extreme heat or aggressive oils

How fast do you ship?

Most orders ship the same or next business day. We offer UPS and FedEx shipping with tracking. Free shipping on orders in continental U.S.

What is your return policy?

We have a 30-day return policy on unopened and unused items in original packaging. Opened seal kits and diaphragms are not eligible for return due to their precision nature. Please contact us before returning any item.

Do you offer warranties?

Yes. All seal kits and diaphragms come with a 1-year warranty against manufacturing defects. Warranty does not cover damage from improper installation or misuse.

Can you help with serial number specific fitment?

Absolutely. Many breakers have variations within the same model. Send us the serial number (or a photo of the data plate) and we’ll confirm the exact kit or diaphragm you need.

Do you ship internationally?

Yes, but shipping costs and customs fees vary. Contact us at 844-2-SEALKIT or email us sealkitcity@gmail.com for a quote.
