Adaptor for Packing

The split device made of ESC material has been pressure tested to 100 PSI / 6.9 Bar. The typical applications for the Adaptor are well within this limit. Should you have a higher-pressure application and still require a split device, contact EnviroSeal.

Composite Adaptors have a built-in gasket. For metal Adaptors customer must supply their own gasketing material. 

Yes.  Packing SpiralTrac Adaptors are typically used to help large equipment keep running until the worn shaft/sleeve can be replaced

The two halves are machined to a smooth finish to ensure total face contact when tightened together with the socket-head cap screws that are supplied with each device. Split metal Adaptors are supplied with a gasket sealant which should be applied for each half.  Refer to installation instruction for details.

The turbulence in the seal cavity will not be changed with the standard Adaptor. What is important is to protect the environment around the seal itself, and that is achieved with this design. An option, should you wish to control the turbulence in the seal cavity, is to order the Adaptor with a nose piece that will fill the entire void of the seal cavity. It is important to note that this option can be used only when there is enough first obstruction space available.

No. We recommend to use flush with all SpiralTrac Adaptors.

SpiralTrac Adaptor can be your answer when:

• Box bore too big/small (for gasket of seal)
• Bolt pattern too big/small (for seal mounting)
• Shaft wear (moving seal closer to clean part of shaft, closer to bearings)

Split SpiralTrac Adaptors are available in ESC and metal.
