High Purity Fittings
At Fluid Controls, we offer a wide range of high purity fittings including a selection of high purity pipe fittings and tubing. As proud Parker distributors, we supply their comprehensive Parker Vacuseal™ range, which includes UHP mini butt weld and face seal high purity fittings. Alongside this, we also supply Valex UHP tubing, weld fittings and coax dual containment tube and fittings for critical small bore and bulk gas applications.
High purity fittings
Valex weld fittings
Valex produces the most respected tubing, fittings and total containment components used in today’s ultra-high purity gas delivery systems. Valex weld fittings have been long-established as the components of choice by producers of semiconductors, and manufacturers of semiconductor equipment.
Face seal fittings
Parker Vacuseal™ UHP fittings are designed as leak-free components for critical applications where ultra-high pure conditions are required. VacuSeal™ vacuum fittings, with their mating gasket and toroid design, provide a metal-to-metal seal with leak-free service from vacuum to positive pressure.
Automatic butt weld fittings
Parker Butt weld fittings are designed for applications requiring the reliability of a welded tubing system. They were developed specifically for installation using automatic, orbital TIG (Tungsten/Inert Gas) welding equipment. These high purity pipe fittings offer the easiest, fastest and most reliable way to fabricate welded systems. Automatic butt weld fittings are available in 316, and 316L stainless steel in straight unions, tees, 90° elbows and crosses. Automatic butt weld ends are also available with male pipe and compression tube connections.
The Ultra-seal coupling is designed to affect a helium leak-tight seal when the face of the gland makes full metal-to-metal contact with the face of the body, compressing the O-ring in the body groove. Ultra-seal components are available in standard 316L, 316L VAR, 316L VIM/VAR stainless steel and can be supplied with extremely low Ra internal surface finishes to meet the requirements of ultra-high purity tubing systems.
Mini butt weld fittings
Parker Vacuseal™ UHP fittings are designed as leak-free components for ultra-high purity applications. Mini butt weld fittings provide compact, ultra-high purity solutions for use with orbital weld equipment. Their unique machining and surface enhancement prevent outgassing and inhibit corrosion.
