Rings

O-Rings

O-Rings

Rubber O‑rings are toroidal elastomer seals—available in materials like NBR, EPDM, silicone, Viton, and PTFE—designed to fit into grooves and compress between surfaces, providing versatile, leak‑proof sealing under static or dynamic conditions, resistant to extreme temperatures, pressures, chemicals, and abrasion, while being cost‑effective and easy to install

Key Features:

  • Simple, compact design: Round cross‑section makes them easy to manufacture, install, and replace with standardized groove systems

  • Versatile sealing: Excellent for both static and dynamic use—including rotary, axial, and reciprocating motions

  • High pressure capability: Can seal under pressures up to ~1500 kg/cm² with backup rings

  • Durable & wear-resistant: Materials like polyurethane provide strong abrasion resistance; overall longevity reduces replacement frequency

Dual Leaf Sealing Ring

A robust spring‑loaded assembly of overlapping stainless‑steel seal leaves mounted between the kiln riding band and hood, it dynamically adjusts for thermal expansion and shell runout, creating a pressured seal that prevents material loss, eliminates air infiltration, and enhances operational efficiency and longevity

Key Features:

  • Exceptionally low leakage – achieves ≤1–3% air ingress, significantly better than single-leaf designs (3–5%)

  • Dual-overlap structure – two spring-steel leaf sets sandwiching a ceramic fiber blanket enhance sealing and thermal insulation

  • Spring-loaded flexibility – leaves dynamically follow shell runout, radial/axial kiln expansion, and correct eccentricity

  • Durable materials – constructed from spring-tempered stainless steel leaves for wear resistance and longevity

  • Energy-efficient – minimized false air improves thermal efficiency, cuts fuel consumption, boosts kiln capacity

Buffer Ring

Buffer Ring

Buffer rings are robust shaped seals—typically crafted from polyurethane or nitrile rubber, often with a PTFE/rubber energiser—designed for hydraulic systems to absorb pressure spikes, protect rod seals, prevent extrusion and fluid leakage, and extend component life under cyclic loads and harsh environments

Key Features:

  • Pressure‑Spike Absorption - Acts as a cushion against sudden pressure surges, protecting the primary rod seal from damage

  • Extrusion Prevention - Incorporates backup or anti‑extrusion rings (PTFE, PA) to prevent seal material from deforming under high load

  • Low Friction Sliding - Often features PTFE or polyurethane slide rings and smooth lips to reduce friction and stick-slip in high-speed applications

  • Medium to Heavy‑Duty Use - Engineered to withstand pressures up to 400–600 bar and speeds up to 0.5 m/s, suitable for robust hydraulic systems

Square Ring

A Square Ring is an axial-static sealing element with a square cross-section designed for high-pressure and low-deformation sealing—offering superior extrusion resistance, minimal twisting, and reliable tightness without needing a backup ring. Ideal for flanges, valves, and static seals, available in materials like NBR, EPDM, and FKM, and rated up to ~50 MPa 

Key Features:

  • High extrusion resistance & dimensional stability — excels under pressure (up to ~50 MPa) without deforming

  • Large sealing surface — square profile increases tightness vs round O‑rings

  • Static–only use — ideal for axial/radial static seals; not suited for dynamic applications

  • Material versatility — available in NBR, EPDM, FKM (Viton), Silicone, HNBR, FFKM, PU, etc.
