# Piston Rings

RigForce supplies engine piston rings as individual rings, one-cylinder packs or defined engine sets. Match the ring positions and standard or repair-size designation to your piston reference, and state whether quantities refer to rings, packs or sets.

### Incoming and production checks

We evaluate suppliers and carry out incoming and production checks to identify nonconforming parts before they move further through the process.

### Finished parts and dispatch

We inspect finished parts and check packing and outgoing goods before dispatch, helping catch problems before they reach your warehouse or workshop.

### Issues and corrective action

Nonconforming parts are identified and handled through rework, return or scrap, as applicable. We investigate problems and follow up corrective action to help prevent the same issue recurring.

### Ordering across your parts list

We handle enquiries across categories and part references, considering smaller quantities and stock availability by reference. Your quotation confirms order contents, availability, packing and delivery.

### Delivery updates and shipping coordination

One contact providing multilingual support provides order progress updates and packing confirmation. We coordinate warehouse, packing and export arrangements, shipping documents and shipment tracking, so you can plan for the delivery.

### Support after arrival

We follow up after arrival and coordinate sales and engineering input on concerns, giving you a clear contact for reviewing order or product issues.

## Ring quantities that match your order

We distinguish an individual ring from a one-cylinder pack or engine set in the quotation. The specified ring positions and any required expander are clarified against the reference rather than inferred from a set label.

## Help matching rings to the piston

Your piston or ring reference and engine information can start the enquiry. We can help confirm ring position, profile and axial height, together with the standard or exact repair-size designation required.

For oversize piston rings, include the piston reference and the specified repair size. State whether the quantity means individual rings, sets for one cylinder or sets for a complete engine; ring position and axial height must also match.

## Engine applications

Catalogue examples include Andoria S320 applications. Ring suitability requires confirmation against the engine, piston reference, ring position and specified standard or repair size.

## Frequently asked questions

Can you help identify rings from the piston reference?

Yes. The piston reference and engine application provide a starting point. We can help confirm the ring positions, profiles, axial heights and any expander requirement.

Does one ring set cover a cylinder or the whole engine?

That is defined in the quotation. We distinguish individual rings, one-cylinder packs and engine sets, with the relevant positions and quantities stated for your order.

What quality information is available?

Applicable checks and available records vary by reference and order. Our team can clarify these before you order.

Can I order a small quantity or mix parts?

We can discuss smaller quantities and check stock availability for your references. You can also combine different models and parts categories in one enquiry.

When can you deliver?

Availability and delivery arrangements are confirmed in the quote for your requested references and quantities.

Who handles a concern after delivery?

Your RigForce contact will coordinate the review with the relevant team.
