Rubber Mouldings

Our experience in the rubber moulding industry spans decades, during which time we have gained a vast amount of knowledge about custom designed rubber mouldings.

Our mouldings have been used in domestic appliances, downhole applications, offshore equipment, telecommunication equipment, valves, plumbing equipment, food and drink production, satellite dish production, electronics equipment and rolling stock.

'O' Rings

At Bovill & Boyd we hold an extensive stock of O Rings, both metric and imperial. In addition our access to comprehensive stockholding/production facilities in the UK Midlands, Luxembourg & Italy allows Bovill & Boyd to supply a significant range of O'Rings.

Viton, Nitrile and Silicone Cord are readily available in both Metric and Imperial. Other materials and less standard hardnesses can be manufactured to your requirements. If required this cord can then be subjected to one of two processes in order to make O'Rings in non standard sizes whilst avoiding the moulding cost. Scarf joined & vulcanised is a common process used to join cord into rings, an alternative to this is another process which gives a stronger join - Just ask for a Moulded Join O'Ring. PTFE Solid and Spiral Back up Rings are also available.

Rubber Extrusions

During our many years of involvement with rubber extrusions we have built up a network of reliable, quality manufacturers each with their own areas of speciality. This means that we can find the most suitable producer for your rubber extrusions whatever the dimensions, material or quantity.

Other production facilities include extruding and parting off to make bushes to your specifications. This method is most commonly employed when the thickness of a washer will lead to concavity on the OD should it be punch cut. The most efficient method of production in these circumstances is extruding thereby maintaining a tighter tolerance on the OD & ID.

Our experience ranges from Tubes, Cords, Glazing Profiles, Beading, Door Seals, Gaskets, Edge Protectors, Dust Seals and Bushes to larger fenders and piggy backs. A broad variety of materials are available, both solid and sponge, as indicated for your perusal.


Our production facilities for punch cut parts are among the most varied in the gasket industry. They range from skilled hand fabrication to the fastest, fully automatic, production of gaskets and washers from a wide range of materials in sheet, strips, discs & pads, self-adhesive backed or plain.

Our range of parts includes both self adhesive backed and kiss-cut self adhesive backed on coated backing paper. Kiss-cut components allow ease of removal from the backing paper for an environment where speed is of the essence.

Components are available in a wide range of materials to your drawings. A representative example of these materials is detailed. Many of these are available from stock in a variety of thicknesses.


Our heavy-duty hose protection has exceptional anti-crushing performance and high abrasion resistance. It is self-lubricating to reduce wear on hose and cable and is easy to fit which reduces the chances of industrial injury.

This excellent hose protection is suitable for wrapping single or multiple hose bundles and is available in a variety of sizes that can wrap diameters from 12mm to 200mm. Available in both black and yellow from stock in East Kilbride. Sizing and technical information available in the downloads section.

EMC (Electromagnetic Compatibility) Gaskets

We supply a selection of products to help achieve EMC (Electromagnetic Compatibility).  Our product range includes extruded and moulded conductive silicones/fluorosilicones for environmentally harsh requirements.

For less harsh environments, we can provide various solutions including vent panels, finger strips, fabric wrap & conductive foams.


Bonded Seals

Bonded seals are based on a rectangular section, metal washer, with a trapezoidal shaped ring of vulcanised rubber bonded to the inside. You can choose the material for the washer and the rubbers to best suit the purpose. This seal is primarily used in high-pressure environments where copper washers are unsuitable.

A further alternative is Self Centralising Bonded Seals which have an extra lip on the ID of the rubber. This centres the seal at its location and will eliminate leaks with the added advantages of easy installation and reduced assembly time.

Fluid Seals

From the standard, off-the shelf to the sophisticated custom designed product we can help find the most appropriate seal for your application. Whether it is static hydraulic or explosive decompression resistant environments, we have the experience, knowledge & ability to help you find the perfect seal. Single & Double Acting Seals, Rubber & Metal Cased Wiper Rings, U Rings, Wear Rings & 'T' Seals form only a part of the comprehensive product range applicable to this specialist field. A variety of compounds are available and we have at our disposal the relevant skills to help provide the ultimate sealing solution.

Shims & Washers

We can supply you with a wide range of Shims. From individual Solid Shims to Shim Packs with combinations of solid shims in various thicknesses. Also available is Easipeel Laminated, which combine layers of Precision Foil surface bonded together. We can combine Solid & Easipeel to give you maximum flexibility.

& Light Pressings
Washers, Lockplates and a wide range of Tab Washers form part of our standard range. Machining & Other Products Graded Spacers, Joint Rings, Bushes, Bolts, Pins, Sleeves

Project Management - Piggyback Assemblies

Since 2000 Bovill & Boyd have supplied piggyback assemblies for dozens of projects to various clients.

Block material is dependant on the project and could be rubber, polyurethane or plastic. Banding systems also vary from Carbon Steel strapping for a short term life-span to Stainless Steel, Alloy 625 or Titanium. Kevlar straps and bolts in varying materials are also an option for a potentially faster pipe-lay.

Project Management - Heat Exchangers

Bovill & Boyd's continued strive for diversification is demonstrated clearly by its relationship with Therco, the UK's largest fabricator of Air Cooled and Tubular Heat Exchangers.

With additional expertise in the manufacture and repair of tubular heat exchangers, the exclusive alliance between B&B and Therco provides operators in the oil and gas industry both up and downstream with a very capable resource.

In addition to the above as the new owners of the Serck Industrial library of drawings and part numbers, Therco are the worlds only manufacturer of genuine Serck Industrial spares for amongst others, the Powergen (Nuclear and Coal Fired etc), Traction, Industrial and Marine market place.
