Hydraulic and Pneumatic Seals...since 1975
DBM L26 is a three piece double acting compact seal which consists of one fabric reinforced elastomeric sealing element and two thermoplastic guide back-up rings
PRODUCT ADVANTAGES
APPLICATION
Mining equipment , iron and steel industry , marine hydraulics and earth moving equipment.
INSTALLATION
DBM profile L26 is designed for installation in open or closed grooves. We recommend the open groove design for pistons that are smaller than Ø 50 mm. It is important that the assembly tool has to be soft material, and no sharp edges. For the installation of the seal element needs to be lubricated with oil system.
NOTES
For special applications that require high temperatures , our DBM L26 is being manufactured with reinforced cotton fabric with FPM and special mixture of PTFE guide back-up rings.
MATERIAL: POM / COTTON FABRIC / NBR 80 SH
