Hard Yet Flexible

A polyurethane ring is both hard yet flexible, which is one of the unique properties of this type of material. It's a very strong and resistant material, allowing it to be used under both high loads and high pressure. However, it's also a flexible material, which when bent or pushed out of shape will return to its original shape quickly. This means that you can use it for a wide range of applications without it breaking or bending too much to lose its shape. You'll find it takes a lot for this type of O-ring to become damaged, which is why urethane O-rings are so popular with our clients today.

A Durable Solution

Polyurethanes are very strong and durable, meaning your O-rings will last far longer than other ones you may have used in the past. You'll find that they are unlikely to tear or get worn down even when used for an extended period of time, helping you to save money on replacements. No matter what type of motion you put them through, you'll find that they won't break easily and will last a long time. This can help you to save a fortune when you don't need to replace them too often, which is a common issue with other materials.

Versatile for a Range of Business Operations

O-rings have many different uses, and you'll find that polyurethane O-rings are a great option for almost any operation that requires O-rings. They are excellent for handling a range of chemicals and conditions, offering you great results no matter what you put them through. We know that many people worry about using O-rings in high temperatures, humidity and with chemicals, but this material is ideal for use in any of these conditions. It will retain its strength and composition no matter how you use it and can be attached to common materials, including plastic and wood.

Ideal for Use With Food Production

Any process that requires seals and O-rings within the food industry needs even more consideration when it comes to the type of material you use. The good thing about polyurethane O-rings is that they are sterile, which means they are resistant to mould and mildew. This industry requires more care and attention when handling things that consumers will eat, but our team can recommend the best options for your needs.

A Good Value-for-Money Solution

When considering the benefits of polyurethane O-rings, cost is something we encourage you to think about carefully. You may be surprised to learn that this is one of the cheapest materials to make O-rings from, and usually it's cheaper to buy and produce them than plastic parts. As well as being radiation resistant and offering you many benefits, you'll notice that your money goes further when you switch to this type of O-ring.

What is the Best Material for Your Next O-Ring Purchase?

Innovation, emerging technology, and several new material options are encouraging fluid power industry OEMs and cylinder builders to take a fresh look at a trustworthy and tested old friend' the polyurethane (PU) O-Ring. Known for their durability, resilience, and adaptability, PU O-rings have found their rightful place in hydraulics, where static seals are pivotal in preventing leakage between connecting components in fluid power systems, more specifically between connecting rods and piston heads, and cylinder tubes and glands. Often considered secondary to dynamic seals, these seals are instrumental in maintaining pressure where it matters most.

The polyurethane O-Ring typically provides sealing between a gland and a cylinder bore or a rod and a piston. However, understanding the PU O-Ring's complexities, particularly in medium and heavy-duty technical applications, is not straightforward in today's multifaceted industrial environment. It requires advanced manufacturing, technology expertise, and proven processes for managing the changing landscape regarding multiple material options.

Here are five facts to remember when considering the Hallite 003 PU O-Ring for your next hydraulic cylinder application.

1. It is a singular solution and an efficient alternative to a traditional two-piece elastomer O-ring and backup combination. The Hallite 003 PU O-Ring can be standardized to a configuration commonly addressed with different components, making it capable of delivering across all duty cycles and a wide range of pressure requirements.
2. It is a compact solution for static applications when the space for a seal in the cylinder is limited. Since it can fit in traditional and industry-normal O-ring grooves, the overall sizing of glands and pistons can be reduced.
3. Due to fewer components, it offers less risk of assembly errors, concerns, and risk if incorrectly orientated.
4. Fewer components also require less purchase and stock handling.
5. Its Hythane material offers both resilience and extrusion resistance, eliminating the need for additional anti-extrusion back-up rings. Hythane 591 high-performance polyurethane, ensures effortless installation and reliable high pressure sealing. For more demanding low-temperature conditions, alternative material options, such as Hythane 181, are available.

Cylinder builders can rely on the 003 PU O-Ring to reach performances of up to 500BAR in a singular solution, simplifying the design process with fewer components. High tensile strength allows the O-Ring to withstand high pressure and shock loads. Notably, the PU O-Ring enables Hallite to provide a complete static sealing solution today with endless potential as we collaborate with customers to explore additional use applications, such as valves and hydrogen.
