RH Nuttall is a leading manufacturer and supplier of all flat section rubber gaskets. Our in-house cutting facilities allow us to produce bespoke parts both quickly and at competitive prices. Solid rubber gaskets are made to any flat shape, from simple round or square designs through to items with numerous holes and slots – should they be required. Current capacity enables us to manufacture over 500,000 rubber gaskets per week to a myriad of industrial sectors including construction, marine, defence, medical, agriculture, and pipeline.

A rubber gasket is selected to house between two mating surfaces to alleviate parts rubbing and deteriorating and acts as a perfect barrier and seals the two mating surfaces when pressure is applied. It’s far more cost effective to replace a rubber gasket than the metal housing if deformation has occurred. To aid in third-hand fixing, a double sided adhesive is sometimes applied – depending on the application.

In comparison to expensive moulding tools, we manufacture our bespoke flat solid rubber gaskets from relatively inexpensive woodforme tooling, so there’s no compromise to design, and outlay is kept to an absolute minimum.

The tooling we use is then strapped to computerized machinery, stamping out the desired shape required from the chosen base material of rubber.

With over 20,000 tools already in stock, we might even have the size you’re after. Please ask a member of our sales team for more information.

Our bespoke rubber gaskets can be made as small as a few millimetres right up to 1000mm in length or diameter.

We also often produce multi-thousand runs, simultaneously, to one-off parts. Every size and quantity is catered for.

Upon selecting a rubber gasket for a particular design, it’s important to understand the function of different grades of rubber compound, and chose carefully given the application in question. To the untrained eye, rubber is simply a durable, yet flexible black elastomer, however this couldn’t be further from the truth.

The rubber gasket is carefully considered before production commences, and a compound is selected that suits the application in question. Below is a brief overview of the main grades of rubber we manufacture our rubber gaskets from:

SBR/Commercial

  • General purpose rubber. Low/medium duty applications
  • Cost effective sealing solution where application isn’t subjected to extremities
  • Available in a variety of thicknesses, with most held in stock
  • Excellent physical properties including abrasion resistance, good tensile strength, and low compression set
  • Not to be selected where petrol, chemicals and such are present

Neoprene

  • Multi-purpose base material – our most commonly cut base material
  • Suitable for applications where sea water, mineral oils, and grease are present
  • Excellent acid resistance
  • Good ozone and oxidation levels of resistance
  • Available in a variety of thicknesses – most held in stock

EPDM

  • Ideal for applications where water is present
  • Available in WRAS approved form
  • Good resistance to fresh and sea water, oxidation, ultra violet, ozone aging and weathering
  • Good temperature resistance, abrasion resistance, animal and vegetable oil resistance
  • Available in a variety of thicknesses, with most held in stock

Nitrile

  • Excellent resistance to petroleum
  • Excellent resistance to oils, aromatic hydrocarbons, mineral oils, and many acids
  • Good abrasion resistance
  • Impermeable to many gases
  • Moderate mechanical properties
  • Available in a variety of thicknesses, with most held in stock

Viton

  • High-end material
  • Excellent resistance to oils, petrol, acids
  • Excellent resistance to temperatures
  • Low permeability to gases

Silicone

  • Exceptional high and low temperature range without failure
  • Thermally sable base material
  • Flame Retardant
  • Excellent electrical insulating properties
  • Good resistance to animal and vegetable oils
  • Good resistance to diluted acids, ozone, oxidation and water absorption.
  • Available in a range of colours

In addition to all of the above grades of rubber, RH Nuttall also manufactures rubber gaskets in a whole host of British Standard Specification materials, if required.

Insertion rubber gaskets are also manufactured by RH Nuttall. This base material has a cotton ply through the cross section of the gasket making the rubber gasket more resilient during its application.

Thicknesses

The thickness of rubber gasket selected can make a huge difference to the sealing quality required. At RH Nuttall we have an experienced and dedicated sales team that will walk you through every step to achieve a perfect seal. The thickness of rubber gasket is generally determined via the base material selected. Most of the grades above can be manufactured from thicknesses as thin as 0.5mm. Increments are then stocked in base material rolls including 0.8mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 15mm, 20mm, 25mm, 30mm and 50mm. We are sure that we will have the answer to thickness with all these thicknesses held in stock. Samples of our base materials are readily available to be sent out for review to ascertain if they are suitable for the application in hand.

Self-Adhesive

RH Nuttall hold a variety of double sided adhesives in stock that can be applied to one or both faces of a rubber gasket. The rubber base material is primed prior to applying the adhesive to ensure a good bond is achieved. Please note that the surface the gasket is being applied to will need to also be cleaned as the adhesive will not stick to grease or dirt. The aim of the adhesive backing is to act as a third hand fixing, allowing the rubber gasket to stay in situ while bolts are passed through the gasket to ensure correct sealing.

Colours

The vast majority of the rubber gaskets manufactured in-house at RH Nuttall come in black or white. Usually, the rubber gasket needs to be hidden in the application and therefore black is the most common choice, however certain rubber materials (depending on volume required) can be manufactured in red, blue, and grey. These materials are subject to minimum order quantities, and only a selection of thicknesses are held in stock.

Standard  – PN16 & PN10

At RH Nuttall we also manufacture a full range of standard pipe gaskets. Rubber pipe gaskets are predominantly manufactured from in-house tooling, which minimises costs and speeds up lead times. Both full face (FF) and Inner Bolt Circle (IBC) gaskets are manufactured on site to British Industry Standard sizes.

Hardness

Rubber Gaskets are manufactured to different hardness, depending on the application and pressure required to create a perfect seal. Rubber is measured on the durometer scale using equipment designed for this purpose. In simple terminology, the scale can be thought of as the difference between the elasticity of a rubber band (approx. 20sh), compared to a car tyre (70sh); both are made from rubber compound, yet display completely different physical properties. Many of the rubber gaskets we manufacture are supplied in a range from 50sh to 80sh, with 70sh being the most standard. Our dedicated sales team are always on hand to offer advice or samples during the estimating process, ensuring we select the correct product first time.
