Spring-energised sealsJames Walker has been manufacturing spring-energised seals since the 1940s.
We recommend the use of these seals for applications that preclude the use of more conventional elastomeric/polymeric seals on arduous duties in areas such as:
• Oil and petrochemical
• Cryogenic plant
• Aerospace
• Food and pharmaceutical processing
• Automotive and general industry
We offer a full range of Unilion® precision-engineered products that meet the following parameters:
• Used successfully on applications at up to 103 MPa/15,000 psi
• Cryogenic duties down to -260°C
• Temperature excursions up to +350°C
• Resistance to corrosive media
• Efficient dynamic operation following long stationary periods
Unilion is available in our Fluolion® range of PTFE based materials. This series encompasses both virgin PTFE and filled variants to suit a wide range of temperature, chemical and pressure requirements.
Unilion seals have no storage period limitation. They can safely be held in stock on-site to meet OEM and maintenance requirements. Additionally, as a single Unilion can perform three sealing duties - static, reciprocating and rotary - stockholding requirements can be reduced, thus simplifying inventory control.

GasketsOur work at the forefront of sealing technology gives us a clear understanding of the roles that different types of gaskets play in flange sealing.
Gaskets can be classified into three main categories (non-metallic, semi-metallic and metallic) and each has its own advantages depending on the operating and service conditions in which they will be expected to perform.
A gasket is often the most practical and cost effective way to seal a bolted flange joint, however the problem for designers and maintenance engineers is to select the correct type to ensure the integrity and safe operation of their valves and equipment. This is where our experience lies.
Metaflex®
Spiral-wound gaskets generally used for higher temperatures and pressures.
Metakamm®
Metallic kammprofile-type gaskets frequently used on heat exchangers.
Insolion®
Isolation gaskets covering the widest possible performance envelope, including Shell TAT approval.
Fluolion®
Range of PTFE gaskets providing outstanding chemical resistance for duties where hygiene and non-contamination are essential.
Supagraf®
Graphite sheet gaskets combining chemical resistance with an exceptionally wide temperature range.
Centurion® X, Chieftain® X and Sentinel® XHigh performance range of CNAF gaskets produced to any size, shape and quantity.
Moorside® API metallic ring joint gaskets for high pressure oilfield applications and process industry duties.

Our RotaBolt® technology has been helping to ensure bolted joint integrity for over 30 years. Built on the science of measurement, RotaBolt accurately measures tension so that it can be correctly achieved, maintained and monitored. The technology continues to evolve, with the latest development offering real-time precision monitoring via remote access to bolted connections in the most critical applications.
We ensure the highest levels of product performance and value through a proven approach of engaging directly with our customers’ experts. In this way the solutions and products we develop are focused on addressing the root cause of issues and delivering results such as improved productivity and safety whilst helping to control maintenance and operational costs.
RotaBolt® RB1 TouchRotaBolt RB1 Touch ensures each bolt is installed to the correct tension and then continues to offer a simple tactile check that this tension is being successfully maintained.
RotaBolt® RB2 TouchRotaBolt RB2 Touch features two tension settings within a single sensor for even greater control and monitoring. The dual load indicator provides an operational tension range, either for overload or maintenance control.
RotaBolt® VisionDesigned with critical yet hard to access applications in mind, RotaBolt® Vision uses a specially developed indicator which appears as an unbroken yellow line across the head of the fastener that can be seen from a distance even in poor visibility situations such as a subsea environment.
Behind the brand
The RotaBolt® took its name from the rotating cap on the head of each stud or bolt which provides a visual or tactile indication that the desired design tension has been achieved and is being maintained.

Health warning: If PTFE products are heated to elevated temperatures, fumes will be produced which may give unpleasant effects, if inhaled. Whilst some fumes are emitted below 300°C (572°F) from PTFE, the effect at these temperatures is negligible. Care should be taken to avoid contaminating tobacco with particles of PTFE or PTFE dispersion, which may remain on hands or clothing. Safety Data Sheets (SDS) are available on request.
Information given in this publication is given in good faith and represents the results of specific individual tests carried out by James Walker or third parties in accordance with the methodologies described in this publication, performed in a laboratory. No representation or warranty is given in relation to such information. Values and/or operating limits given in this publication are not an indication that these values and/or operating limits can be applied simultaneously. While such results may comprise useful additional information and are industry standard tests, they are no substitute for conducting (or procuring from James Walker) your own tests and engineering analysis and satisfying yourself as to the suitability of the product you select. Please also note that a product tested in accordance with the published methodology may not perform to such values in application and/or under different test conditions or methodologies for a variety of reasons, including but not limited to the environment in which it is used/tested or which passes through it or otherwise affects the product, or due to the handling, storage or installation, or due to the effect of housing or other parts. Our personnel will be happy to discuss any historical examples we have of a product having been previously used in a particular application.
