Parker O-RING KITS

  When part numbers are missing, seal dimensions are unknown, and the parts themselves are unavailable from the equipment OEM, these o-ring kits can save the day, not to mention hours of downtime. More than eight different standard kits give you a choice of compounds and o-ring sizes for a wide range of sealing applications. The end result? Multiple sealing solutions for the same cost as a single OEM replacement part. We’ll even build custom kits using any of our 200-plus compounds.

EXTRACTION TOOLS

These unique double-ended tools make life easier for those who have to frequently install or remove o-rings from hydraulic or pneumatic cylinders and equipment. Available in brass or plastic, with or without a convenient carrying case.

ASSEMBLY GREASES AND LUBRICANTS

O-LUBE is a barium base petroleum grease that prolongs the life of synthetic rubber seals. It offers excellent surface adherence and lubrication with inherent water resistance. It is recommended for low-pressure pneumatic systems, as well as reciprocating and low-speed oscillating or rotary applications. Parker O-Lube works well in a –20°F to +180°F temperature range. It is not recommended for silicone, butyl, or ethylene propylene rubber seals, or for use in systems with micronic filters.

SUPER-O-LUBE is a silicone lubricant that can be used with virtually any rubber polymer over temperatures ranging from –65°F to +400°F. Used sparingly, it will provide better environmental protection for the elastomer. It is particularly recommended for high pressure systems, as well as vacuum applications. Parker Super-O-Lube adheres with unusual tenacity and is highly moisture resistant. In addition, it will not clog 30-micron filters. O-Lube and Super-O-Lube are available in a variety of package sizes for use in kits, tool boxes, and more.

O-RING SIZING CONE

A unique measuring cone and circumference “Pi” tape provide quick and easy o-ring sizing information to determine the nearest standard Parker o-ring size. Please note: the cone and tape do not measure actual dimensions of a part and cannot be used for pass/fail inspections.

• They seal over a wide range of pressure, temperature and tolerance,
• Ease of service, no smearing or retightening,
• No critical torque on tightening, therefore unlikely to cuase structural damage,
• O-rings normallyng compound first, as the selected compound may have significant influence on gland design parameters. essentially, the application determines the rubber compound; the primary factor being the fluid to be sealed. 
• The elastomer however, must also resist extrusion when exposed to the maximum anticipated system pressure and be capable of maintaining good physical properties through the full temperature range expected. 
• In dynamic applications, the selected material must also have the toughness and abrasion resistance so important in reciprocating and rotary seals. 
• polymer families - select a polymer to view the available compounds offered within that family.

• In many cases an o-ring can be reused, an advantage over non-elastic flat seals and crush-type gaskets,
• The duration of life in the correct application corresponds to the normal aging period of the o-ring material,
• O-ring failure is normally gradual and easily identified,
• Where differing amounts of compression effect the seal function (as with flat gaskets), an o-ring is not effected because metal to metal contact is generally allowed for,
• They are cost-effective where to begin in designing an o-ring seal, it is best to determine the o-ring
