DBM TPM is a five piece double acting compact seal which consists of one elastomeric nitrile rubber sealing element , two polyester elastomer back-up rings on both sides to prevent extrusion into the sealing gap and two special profiled guide rings produced from thermoplastic to absorb transverse forces.

PRODUCT ADVANTAGES

• Superior sealing performance
• Economic sealing and guiding solution
• Simple groove design , one-piece piston possible
• Long service life
• Simple snap installation

APPLICATION:

Construction machinery , fork-lift trucks , injection moulding machines , agricultural machinery , cranes and standard cylinders.

INSTALLATION:

Easily assembled into one-piece piston because the back-up rings and guide rings are been produced in split forms. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

NOTES: For special applications that require high temperatures , DBM TPM piston seal is manufactured in FPM and PTFE material.

Note: The above data are maximum values and cannot be used at the same time.

Note: It is recommended to have 50% to 90% of the working surface material contact area value.
