We manufacture high quality hydraulic seals; our products are made of premium quality materials and are highly durable. We offer a wide range of sizes and also manufacture products as per our customer’s needs. Hydraulic Piston Seals maintain sealing contact between the piston and the cylinder bore. They are internal to the cylinder head and seal against the cylinder bore, preventing fluid from flowing across the cylinder head. This allows pressure build up on one side of the piston, making the cylinder extend or retract.
The OMM DAS Piston Seal is designed to fit on one or two piece pistons, this piston seal employs a nitrile seal for high seal ability, pu split back-ups for extrusion resistance, and two split bearing rings of delrin/nylon/hdpe.
The Compact Seal is a double-acting seal and guide element comprising of a rubber seal, two split support rings and two split bearings, located either side of the seal. The profile seal ring seals in both the static and dynamic range whilst the backup rings prevent extrusion into the sealing gap.

1. Features:
Piston seal profile consists of four or five -piece seal set with one main sealing component, one T shaped energizer ring and two anti-extrusion ring which support the seal on both sides and prevent contamination to the energizer and main seal ring.
2. Properties:
Double acting, Allow large radial gaps due to backup rings, Very good extrusion reliability, High resistance to abrasion, Low friction, Free of stick-slip, High contact pressure through rubber profile ring, No extrusion into the radial sealing gap.
3. Application:
(i) Mobile Hydraulics
(ii) Machine tools
(iii) Agricultural equipment
(iv) Standard cylinders.
