Frequently Asked Questions

How do we make our gaskets?

Gaskets are cut from the right material for the job the gasket has to do. They are typically manufactured from flexible materials and are cut by knife, press, waterjet, or laser.

To make a gasket:

• Specify dimensions

• Specify material (or provide material requirements)

• Send an enquiry to the manufacturer

Once we receive an enquiry, we determine the most suitable method to manufacture your gasket based on the size, material and lead time required.

Large-Volume Supply

Do you handle large-volume gasket orders?

Yes — large-volume production is one of our core strengths. We regularly supply OEMs and industrial customers who require consistent, repeatable quantities on an ongoing basis.

What is your minimum and maximum order quantity?

We supply everything from small prototype batches to very high-volume production runs. There is no strict minimum, but volume manufacturing is where our pricing and turnaround times are most competitive.

Can you support long-term, repeat gasket supply for OEM contracts?

Absolutely. We work with many UK and international manufacturers who rely on us for consistent, repeatable supply. We can produce the same part reliably for years, with full traceability.

Do you offer favourable pricing for bulk or repeat orders?

Yes — larger quantities benefit from improved material utilisation, machine optimisation and economies of scale. We are happy to quote based on annual or scheduled volumes.

Can you manufacture custom gaskets at high volume?

Yes. Most of our high-volume production is fully customised to drawings, samples, or specifications. We also create tooling in-house where required.

Lead Times, Delivery & Availability

What are your typical lead times for large orders?

Lead times depend on material selection and order size, but our UK-based production ensures fast, predictable turnaround. We regularly support customers with urgent requirements.

Can you supply urgent or quick-turnaround gasket orders?

Yes — for many materials we hold local stock, allowing us to turn around urgent orders quickly. Contact our team for time-critical projects.

Do you offer stock-holding or scheduled deliveries?

Yes — for regular customers, we can hold stock, schedule production, or set up call-off orders to support uninterrupted supply.

Technical & Manufacturing Capabilities

What gasket materials do you supply?

We manufacture gaskets in a wide range of materials, including NBR, EPDM, silicone, Viton™, cork, sponge, foam, compressed fibre, non-asbestos materials and many more.

Which cutting methods do you use?

We offer die-cutting, waterjet cutting, kiss-cutting, CNC cutting and custom tooling depending on your volume and tolerance requirements.

Can you work from samples, drawings, or CAD files?

Yes — we can manufacture from technical drawings, DXF files, customer samples, or reverse-engineer parts if needed.

How accurate are your tolerances?

We achieve tight, consistent tolerances suitable for industrial and OEM applications. Tolerances vary by material and process — our technical team can advise.

Do you help with material selection?

Yes — whether you need chemical resistance, high-temperature stability, oil compatibility or specific certifications, our experts will recommend the most suitable material.

Quality, Reliability & Compliance

How do you ensure consistent quality across large-volume runs?

We use strict quality control, batch traceability, consistent tooling and repeatable cutting processes to ensure every order meets specification.

Are you certified?

Yes — Ram Gaskets operates under recognised quality standards (ISO etc.). Certificates and test reports are available on request.

Can you provide material certification or conformity documents?

Yes — we can supply relevant certificates, compliance information and datasheets for all materials.

UK Manufacturing Advantages

What are the benefits of using a UK-based gasket manufacturer?

Choosing a UK supplier offers faster lead times, easier communication, reliable logistics, fewer delays and consistent quality compared to many overseas sources.

Can you replace my offshore gasket supplier?

Yes — many customers switch to Ram Gaskets when they need improved consistency, shorter lead times and long-term supply stability.

Pricing & Quotations

How do you calculate pricing?

Pricing is based on material choice, thickness, part size, cutting method, complexity and volume. Higher volumes reduce the cost per unit.

How quickly can I receive a quotation?

We typically provide quotes within 24–48 hours. For complex or high-volume projects, our team may request drawings or material details to ensure accuracy.

Orders, Delivery & Support

Do you ship throughout the UK and internationally?

Yes — we supply customers across the UK, Europe and worldwide.

Can I reorder the same gasket later?

Yes — once we create tooling or a production file, repeat orders are simple and maintain the same quality and tolerances.

How do I request a quote?

You can upload drawings, specifications or samples via our contact form, or speak directly to our sales team for assistance.

General Gasket Questions

How do I remove gaskets?

As they age, some gasket materials may harden or soften and adhere to metalwork. Remove old gasket material carefully to avoid damaging sealing surfaces. Chemicals may assist in some cases. If in doubt, contact us for advice.

What is the difference between a gasket and a seal?

The terms are often used interchangeably. Generally, gaskets are flat, two-dimensional shapes cut from flexible materials, while seals are three-dimensional forms that are moulded or machined.

Where can I buy gasket material?

We stock many grades and thicknesses of gasket material — from papers, rubbers and foams to non-asbestos materials. We can ship sheets or rolls worldwide.

How do you make rubber gaskets?

Rubber gaskets are typically cut or pressed from rubber sheets. The cutting method depends on the material, thickness and quantity required. We can advise on the best method for your application.

What is the right material for my application?

This depends on temperature, pressure, chemical exposure and required durability. Our Gasket Material Selector and Properties of Gasket Materials charts can help — or contact us for guidance.

What thickness material should I specify?

The thinnest material that will seal effectively is usually best. Thickness depends on flange condition and the compression required.

How do I work out the Outer Diameter (O.D.) and Inner Diameter (I.D.)?

The I.D. is the size of the bore. The O.D. is the full outer measurement of the gasket.

How do I determine which Class or Table of gasket I need?

Our Gasket Dimensions Guide provides information for selecting the correct standard.

How do I work out the Pitch Circle Diameter (P.C.D.)?

The P.C.D. is the diameter that specifies the centre of the bolt holes. It is measured from the centre of the bore.
