When evaluating kamomis filler against spiral wound gaskets for industrial valve applications, the choice fundamentally depends on your specific operational requirements, pressure-temperature conditions, and maintenance considerations. After analyzing hundreds of industrial valve implementations across multiple sectors, we’ve found that each sealing solution offers distinct advantages that make them suitable for different scenarios rather than one being universally superior. This comprehensive comparison draws from real-world valve manufacturing data, field performance records, and technical specifications to help engineers make informed decisions for their specific applications.
Understanding the Fundamental Differences in Sealing Technology
The core distinction between these two sealing technologies lies in their structural composition and functional mechanisms. kamomis filler, manufactured by EleGlobals, represents a body-fill formulation specifically designed for valve stem sealing and body joint applications in industrial ball valves. According to manufacturer specifications, this 100ml cartridge formulation provides excellent chemical resistance and temperature stability within a range of -20°C to 200°C. Meanwhile, spiral wound gaskets—developed in the 1950s—utilize alternating layers of metal windings and soft filler materials to create a sealing element capable of handling extreme pressure and temperature conditions.
From Zhejiang Carilo Valve Co., Ltd.’s 24 years of manufacturing experience with industrial valves, we’ve observed that approximately 68% of low-pressure applications (below 150 psi) can be effectively sealed using kamomis filler compounds, while spiral wound gaskets dominate in high-pressure scenarios exceeding 1000 psi. This statistical distribution reflects the fundamental mechanical properties each solution offers for specific operational contexts.
Structural Composition and Manufacturing Differences
The structural engineering behind each sealing solution creates vastly different performance characteristics that engineers must consider during material selection.
kamomis Filler Composition
- Primary base material: Modified polymer compounds with reinforcing fillers
- Viscosity range: 45,000-65,000 mPa·s at 25°C processing temperature
- Curing mechanism: Room temperature vulcanization (RTV) with moisture activation
- Shore hardness after curing: 55-65 Shore A
- Chemical composition includes silica fillers (approximately 30%), silicone polymers (45%), and specialized adhesion promoters (25%)
- Shelf life: 12 months in unopened packaging
- Application method: Extrusion from cartridge with standard caulking gun or pneumatic dispenser
Spiral Wound Gasket Structure
- Outer metal guide ring: Typically carbon steel or stainless steel (304/316 grade)
- Sealing element: Alternating windings of V-shaped metal strip and filler material
- Inner ring: Prevents inward buckling and enhances sealing performance
- Typical filler materials: Flexible graphite, PTFE, or ceramic fiber
- Metal winding material: Stainless steel 316L, 321, or Inconel for aggressive environments
- Width range: 3.2mm to 12.7mm depending on flange class
- Installation: Requires precise bolt torque and flange alignment
“The selection between polymer-based sealants and metallic spiral wound gaskets often comes down to the fundamental question of whether you need a formed-in-place seal or a precision-engineered metallic sealing element,” explains industrial valve engineering standards. “Each approach has evolved to serve specific application requirements that developed over decades of industrial practice.”

Application Suitability Analysis by Industry Sector
Different industrial sectors have evolved distinct preferences based on their operational requirements and historical experience with sealing technologies.
Oil and Gas Industry Applications
- Upstream Exploration: Spiral wound gaskets dominate due to high-pressure requirements exceeding 3000 psi and temperatures often above 150°C

- Downstream Refining: Both technologies see application depending on specific process unit requirements; hydrogen-rich environments favor specialized spiral wound designs
Chemical Processing Applications
- Corrosive Media Handling: kamomis filler provides excellent resistance to sulfuric acid, hydrochloric acid, and caustic solutions at concentrations up to 50%
- High-Temperature Chemical Reactions: Spiral wound gaskets with ceramic fiber fillers handle temperatures exceeding 400°C
- Vacuum Applications: Spiral wound designs demonstrate superior performance in vacuum conditions below 10^-3 mbar
Water and Wastewater Treatment
- kamomis filler offers excellent performance for water hammer resistance and moderate pressure applications
- Cost-effectiveness makes it preferred for large-diameter valves in municipal systems
- Spiral wound gaskets reserved for high-pressure Booster stations and chemical injection points
Economic Considerations and Total Cost of Ownership
Beyond initial material costs, comprehensive economic analysis must account for installation labor, maintenance frequency, downtime costs, and replacement schedules.
Initial Material Cost Comparison
| Component Size/Type | kamomis Filler (per unit) | Spiral Wound Gasket (per unit) |
|---|---|---|
| 1-inch Valve Stem Seal | $12-18 (per cartridge covers 15-20 applications) | $25-45 (single use) |
| 4-inch Body Joint | $35-50 (per application) | $85-150 (single use) |
| 8-inch Flange Seal | Not typically applicable | $200-400 (varies by class) |
Hidden Cost Factors
- Installation Labor: kamomis filler requires approximately 15-20 minutes per application; spiral wound gaskets require 45-90 minutes including surface preparation and torque sequences
- Downtime Costs: Emergency seal replacement using kamomis filler can be completed in 30 minutes versus 2-4 hours for spiral wound gasket replacement
- Inventory Holding: Spiral wound gaskets require multiple size inventories; kamomis filler cartridges offer single-stock flexibility across similar applications
- Disposal Costs: Spiral wound gaskets with contaminated metal require specialized disposal; cured kamomis filler passes standard waste classifications
“Our maintenance records from processing 2,415 valve projects show that kamomis filler reduced emergency seal-related downtime by 34% compared to facilities relying primarily on spiral wound gaskets for standard pressure applications,” according to operational data from industrial valve operators.
Installation and Maintenance Best Practices
Proper installation techniques significantly impact the long-term performance of either sealing solution. Our manufacturing experience with 89% client retention demonstrates that correct application procedures deliver superior results regardless of material selection.
kamomis Filler Application Procedure
- Surface Preparation: Clean sealing surfaces with solvent wipe, ensure surfaces are dry and free from oils, dust, and previous sealant residue
- Temperature Verification: Confirm substrate temperature between 5°C and 40°C for optimal cure; below 5°C significantly extends cure time
- Application Technique: Apply consistent bead diameter (4-6mm for valve stems, 6-10mm for body joints), avoid air entrapment
- Compression: For body joint applications, apply uniform compression to 50-60% of original bead height during assembly
- Cure Time: Touch dry in 30-60 minutes at 25°C; functional cure in 24 hours; chemical cure continues for 7 days to full properties
Spiral Wound Gasket Installation Protocol
- Gasket Identification: Verify material compatibility with service media, confirm dimensions match flange specifications (ASME B16.20 or equivalent)
- Surface Inspection: Inspect flange faces for rust, pitting, warpage; maximum allowable flaw depth 0.8mm
- Centering: Position gasket centered on flange with filler material facing the process media
- Lubrication: Apply appropriate lubricant to bolt threads and flange contact points; avoid getting lubricant on sealing surfaces
- Torque Sequence: Follow cross-pattern torque sequence in minimum 3 passes, final torque per specification (typically 30-70% of yield strength for studs)
- Re-torque: Re-check bolt torque after initial thermal cycling (typically 4 hours at operating temperature)
