The company has certified manufacturing facilities that comply with the strictest requirements for critical medical seals. All materials in the Parker Seal O-Ring Division meet or exceed the U.S. Pharmacopeia Class VI requirements for system and intracutaneous toxicity. They also have stricter requirements for leachates and toxicity. Additionally, Parker offers FDA and NSF-51 materials for food and drink handling equipment, disposable medical devices, and surgical instruments.
Extruded seals
Parker Seals offers a broad range of extruded seals that meet the demanding needs of critical medical applications. These seals are made of clean materials and meet rigorous requirements such as U.S. Pharmacopeia Class VI, which requires the use of ingredients with clear histories of biocompatibility and leachates. NSF 51 materials are a preferred choice for medical equipment, surgical instruments, and food-handling equipment. Parker's modular back-ups are compatible with PolyPak profile materials and are available in a variety of chemical resistance levels.
Extruded rubber profiles from Parker are made from solid or hollow material, and feature high sealing integrity. These extruded rubber profiles are particularly useful in sealing applications that require low-closure force, large-diameter profiles, or unusually sized solid O-rings. Technical sales representatives are available to provide design and product selection assistance and offer on-site assistance for customers. They can also assist in selecting and specifying the right extruded seals for their needs.
For high-temperature, corrosive, or aggressive environments, you can choose between a variety of standard or custom-molded materials from Parker. From extruded silicone profiles to custom-molded metal seals, Parker has a seal solution to meet your requirements. You can even customize the seal's profile to fit the specific application. If you're not sure which extruded silicone profile to choose, you can view a full range of options on the website or request a quote.
If you're looking for an extruded seal with an even stronger lubrication, you can choose from a variety of compounds from Parker. Polyurethane is an organic polymer made by reacting a polyol with a polymeric isocyanate. This polymer lubricant provides excellent tear and permeation resistance. The polyurethane rubber compound from Parker is an excellent choice for sealing applications.
Pressure-sensitive dynamic seals
The most common type of Parker Seal pressure-sensitive dynamic seal is the O-Ring. Designed with a round cross-section to provide a point load, this type of seal is also flexible, which helps it withstand low-pressure conditions. While a higher squeeze can increase the ability of the seal to seal, it can also lead to leaking and spiral failure. Fortunately, a good guideline is that you should not exceed 5% of the rated pressure in your seal.
These lipped seals work in the same way as compression ones but do not produce a compression band across the full contact area. Unlike compression seals, U-cups seal in one direction. System pressure energizes the seal lips, creating a primary seal. The resulting compression band helps lubricate the system. A compression-sensitive dynamic seal is characterized by a high contact area, which can cause friction.
When the temperature changes, most objects will shrink. This is not the case with water, though. Different materials have different Coefficients of Thermal Expansion. For example, thermoset elastomers shrink five times faster than metals. In addition, metals shrink much less than thermoset elastomers, and the seal housings shrink more. Consequently, a metal seal is more likely to create a tight seal even when it stretches a few millimeters.
Generally speaking, dynamic seals are defined by the motion of their surfaces. These motions can be reciprocating, rotary, or oscillating, or a combination of them. O-rings, for example, are most commonly used in reciprocating and rotary motions. The two types of dynamic seals are axial, rotary, and radial. The difference between static and dynamic seals lies in the operational factors that can affect the seal's performance.
Tube fittings
A new patent by Parker Hannifin covers a stainless steel flat face sealing ring for use in tube fittings in extreme temperature applications. The Parker Tube Fittings Division developed the new seal design, now available as the Seal-Lok Xtreme line of flat face seal tube fittings. This innovative seal replaces traditional ORFS elastomeric O-rings, which do not meet the high-temperature and chemical compatibility requirements of many applications.
O-rings for Parker's flange tube fittings have a high-quality flare and smooth mating surface. The patented orbital spindle process allows for a seamless connection within 15 seconds. In addition to the increased connection integrity, this process eliminates the need for expensive brazing of the sleeve to the tube. Parker Parflange is available for many industries. Alternatively, you can order these fittings online.
The Seal-Lok end connection is available in metric and inch versions. These fittings feature a longer locknut that virtually eliminates washer damage or potential leaks. These fittings meet or exceed ISO 8434-3 requirements for metric threads. The Seal-Lok connection can be used with a variety of sizes of hose or tubing, and the locking nut is available in both stainless steel.
The ORFS CORG fitting is designed to withstand up to 200% more torque than its rated value. They are suitable for a variety of wall thicknesses, including metric tubes. In addition to being versatile, Seal-Lok tube fittings are ideal for harsh and high-pressure environments. They are also corrosion-resistant, and meet or exceed SAE standards. These high-quality seals also reduce warranty costs.
Chemical bonding agents
Often overlooked, the chemical bonding agents used in Parker Seal products are essential to ensure the highest quality. These ingredients have various properties based on the chemical bonding agents they contain. The type of chemical bonding agent determines a number of the properties of the material, including flexural and thermal resistance. In addition, the chemical bonding agents also affect the product's overall aging and biocompatibility.
Polyurethane is another material used for manufacturing Parker Seal products. This organic polymer is produced by reacting a polyol with a polymeric isocyanate. Several advantages of polyurethane include excellent tear and permeation resistance and superior strength. To get a better idea of the chemical bonding agents used in Parker Seal products, read on. Parker's specialized drilling products make use of these compounds.
Chemical bonding agents help enhance the performance of Parker Seal's common elastomeric components. They are used to integrate these materials with substrates and create cohesive sealing systems. Using this process, we eliminate pinching and handling damage while minimizing the complexity of the installation. Lastly, we're committed to providing our customers with the highest quality products possible. By choosing Parker, you'll get the right chemical bonding agents for your specific application.
Aside from O-Rings, Parker also offers Nitrile Buna-N O-Rings. These materials are available in metric and standard sizes. Their unique profiles address specific application challenges, such as larger tolerance stocks, low seal load, and complex groove paths. The Oil & Gas industry requires elastomers to seal high pressures and handle a wide range of chemical media. With over 40 years of experience, Parker PolyPak rod seals have become the industry standard.
