James Walker Australia Pty Ltd products

A tough, high performance packing, cross-plaited from texturised aramid yarns. Each yarn is uniformly impregnated with PTFE dispersion and a silicone-based lubricant that resists chemical attack at high temperatures. Suitable for a very wide range of media. Excellent abrasion resistance. Long service life with minimal shaft wear. Resilient and responsive in operation.

Devlon A153 is a specially formulated high-viscosity grade of Nylon 66 with superior wear characteristcs. It is yellow in colour. With its improved impact strength and rigidity, this material offers customers a high degree of design reliability when component strength, weight and size are critical. In addition, Devlon A153 has a significantly lower coefficient of linear expansion than normal Nylon 66, which enables customers` components to maintain their dimensional tolerances and clearances more accurately during thermal cycling. This benefit is backed by a long-term service temperature of 100°C, which is significantly higher than that for normal Nylon 66.

Devlon S Grade is a premium grade polyamide thermoplastic with a high molecular weight and superior mechanical properties. It is blue in colour.

We provide the complete engineered solution to on-site problems associated with ductwork expansion. This service is based on the design and manufacturing skills of James Walker Townson in expansion joints and bellows for applications covering all ductwork temperatures and pressures. On-site surveys and full installation are vital aspects of our total service to industry.

Comflex wraps provide a rapid economic solution to the problems of failed expansion joints. Many years of experience of supplying this product has taught us that the emergency answer very often becomes the permanent solution. We offer ex-stock availabilty of all product grades in standard widths of 250mm, 375mm and 500mm from our UK factory.

Single layer joints with an inner surface of PTFE films that are crossed and laminated to produce the ultimate chemical and indestructable barrier. With a zero porosity inner face, that is capable of  performing from  -73°C to +316°C, this is the ultimate material for harsh chemical condition.

Using James Walker Townson`s range of Elastomeric Expansion Joints you get many special features.
