Non-Metallic Gaskets
Engineered to seal a wide range of aggressive media and extreme temperatures
M Barnwell Services is one of the UK’s largest independent stockists and distributors of Non-Metallic Gaskets. Our Non-Metallic Gaskets seal a broad range of applications including extreme temperatures and aggressive chemicals, utilising our broad portfolio of gasket sheet materials.
Non-Metallic Gaskets are composite sheet materials that are frequently used in the low-pressure flat face and raised face flanges. They can generate a static seal between two flange faces and fill the area and deformities of flange faces. They can also successfully stop the leakage of liquids and gases, therefore sections of pipes mainly utilise them. Non-Metallic Gaskets are made out of a number of materials, including PTFE, graphite, rubber, or reinforced fibre. Consequently, they can comfortably compress with low tension bolting. For that reason, the industries have been maximising the use of flange gaskets on their tools and equipment.
The most popular non-metallic gaskets are:
Standard Rubber Seals: Perfluoroelastomer (FFKM), Nitrile (NBR), Hydrogenated Nitrile (HNBR), Viton™ (or FKM/FPM), Ethylene Propylene (EPDM), Silicone (VMQ), Polytetrafluoroethylene (PTFE) Fluorosilicone (FVMQ)
These can all be measured to imperial (BS1806, ISO 3601) and metric (BS4518) sizes, shore hardness and to a range of International, National and industry specifications, grades and approval standards.
We also offer a comprehensive range of quality FEP/PFA Encapsulated Rubber Seals, O Ring Cord and Hot Vulcanised Seals.
Standard Pipe Flange Gaskets
Standard Pipe Flange Gaskets are highly engineered seals to satisfy the demands of the most challenging situations. We have a gasket for your application no matter what application, whether you require it to be food contact compliant, cryogenic, fire-safe, or just a replacement of a failing seal.
STRESS-SAVER® Pipe Flange Gaskets
- STRESS-SAVER® GYLON® 3504
- STRESS-SAVER® XP
- STRESS-SAVER® 370
Perfect for lightweight piping and non-metallic flange applications in which chemical resistance and low bolt are a concern.
In-Line Strainer Gaskets
Practical and affordable method of safeguarding valuable downstream equipment – protecting metering devices from hazardous contamination in the pipeline. The stainless steel mesh serves as a sieve to filter out weld beads, grit, pipe scale, and other contaminants from the process fluids.
Lubrikup® Prolene Boiler Manhole and Handhole Gaskets
Made out of proprietary rubber compounds. Performance grade, Style 6700 Prolene, manway, and handhole ring gasket constructed from a high-performance ShA 85 Ethylene Propylene (EPDM) rubber. Therefore, this grade material is appropriate to use with water, steam, mild acids, and mild caustics.
