3 Seal-Lok Lite Introduction Parker s Seal-Lok Lite fittings combine the traditional versatility of stainless steel Seal-Lok with the added feature of being adaptable to the new Flex Flange product line. Seal-Lok Lite fittings incorporate the O-ring face seal design to form a leak-tight seal. Seal-Lok Lite shaped fittings with SAE straight thread adjustable studs also feature Parker s new Robust Port Stud, which provides improved reliability and easier assembly. Seal-Lok Lite fittings are not a direct interchange with standard industrial O-ring face seal fittings. Seal-Lok Lite s leak-free, compact design makes it suitable for use in applications for low pressure gases and general light duty industrial systems. Design and Construction The Seal-Lok Lite fitting consists of four main components: a body, a sleeve, an O-ring and a nut. The body, sleeve, and nut are manufactured from 36 stainless steel. The Seal-Lok Lite Fitting Body: Seal-Lok Lite fittings are manufactured in the most popular stainless steel sizes and configurations. The body is manufactured with Parker s CORG (Captive O-ring Groove), which keeps the O-ring captive during installation. Straight bodies are machined from cold drawn bar stock, ensuring consistent dimensional tolerances, improved strength and better surface finish. Shaped Seal-Lok Lite fittings are manufactured from a one-piece forged construction. This forged construction provides added strength and longer service life, while eliminating the potential leak path associated with multi-component brazed fittings. The Seal-Lok Lite Fitting Nut: Seal-Lok Lite tube nuts are machined from cold drawn bar stock. The Seal-Lok Lite tube nut is not interchangeable with the standard ORFS tube nut, as it is much shorter, more compact, and incorporates a metric thread. The Seal-Lok Lite Parflange Sleeve: The preferred method of making a Seal-Lok Lite connection is by using the Parker Parflange machine to create the 90 flange on the tube end. The sleeve provides a contact shoulder for the nut and supports the flange and tubing. The Parflange process provides the following advantages: Several times faster than brazing No special pre- or post-flange cleaning Cleaner and safer than brazing Eliminates a potential leak path associated with braze joints The Seal-Lok Lite fitting uses a standard Parflange sleeve and tooling. See Equipment section for the available Parflange tooling. The Seal-Lok Lite Braze Sleeve: A second method of sleeve attachment is with the braze sleeve. The sleeve is brazed to the tube end as shown in Fig. B3. The flat, smooth surface of the braze sleeve seals against the O-ring when fully assembled. The holding power is provided by the braze. An additional method is a butt weld connector (TLW) that is also used with a tube nut. It is designed especially for orbital welders.

4 How Seal-Lok Lite Fittings Work The Seal-Lok Lite fitting body face contains a 70 durometer, Nitrile O-ring (N0674) that is held captive in a precision machined groove. As the nut is tightened onto the fitting body, the O-ring is compressed between the body and flat face of the tube flange or braze sleeve to form a tight, positive seal. Seal-Lok Lite Size Max. Inch Tube Wall Max. Metric Tube Wall Note: For wall thicknesses outside the recommended range, contact the. As the two faces come in contact, further tightening of the nut produces a sharp rise in assembly torque. A solid pull of the wrench at this point, to recommended assembly torque, completes the assembly. The sharp torque rise gives a solid feel at assembly, minimizing the possibility of over tightening. Table B Recommended Max. Tube Wall Thickness Because the sealing surfaces are flat and perpendicular to the assembly pull, they remain virtually free of distortion during assembly, giving Seal-Lok Lite fittings practically unlimited remakeability. The O-ring should be inspected at each disassembly and replaced when necessary. See the O-ring section for replacement O-rings. Flex Flange Assemblies A unique feature of the Seal-Lok Lite fitting line is the adaptability to a line of light-duty flexible corrugated stainless steel tubes. The Flex Flange assembly is a complete flexible 36 stainless steel tube routing system. These factory pre-made assemblies are available in 3/8", /", 3/4" and " tube sizes in a variety of assembly lengths. The Flex Flange line offers working pressures up to 50 psig without permanently deforming the stainless corrugated assemblies. Flex Flange tube should not be used in applications: Where repeated movement or extreme vibration occurs Involving chlorides or salts As support for other components Fig. B4 Seal-Lok Lite works with inch or metric tube, hose, and Flex Flange assemblies. Assembly and Installation Please refer to Section T for the assembly and installation instructions for Seal-Lok Lite fittings. International Acceptance Versatility: The versatility of the Seal-Lok Lite fitting is shown in Figure 4. A single Seal-Lok Lite fitting will mate with inch and metric tube, hose (Push-Lok and GPH), and Flex Flange. The universal tube nut and fitting body are used with either inch or metric tube, thus saving on component costs. The fitting body without the nut and sleeve is very popular as a hose/flex Flange adapter.
