The Vital Seal for Rotating Equipment
In the world of industrial maintenance, the reliability of a pump or valve is only as strong as its compression packing. Kriloha Ltd. is a premier manufacturer of high-performance braided packings, engineered to provide a dynamic seal for rotating shafts, reciprocating plungers, and valve stems. Our packings are designed to minimize leakage, reduce frictional heat, and protect expensive hardware from premature wear.
From high-speed centrifugal water pumps to aggressive chemical agitators and high-torque marine stern glands, Kriloha Braided Packings offer the mechanical stamina and chemical agility required for the world’s most demanding fluid handling systems.
What is a Braided Packings?
Braided packing, also known as Gland or compression packing, is a versatile mechanical seal manufactured by interlocking high-performance fibers—such as PTFE, graphite, or synthetic PAN—into a dense, square cross-section to prevent fluid leakage along the rotating or reciprocating shafts of pumps and valves. These fibers are vacuum-impregnated with lubricants to create a self-replenishing “lubricant reservoir” that reduces friction and dissipates heat. During installation, multiple rings are compressed within a stuffing box by a gland follower, forcing the material to expand radially against the moving shaft. This creates a durable yet flexible barrier that typically allows for a controlled, microscopic “leak-off” of fluid to cool the interface and protect expensive hardware from thermal damage and wear.

Technical Specifications & Compliance
At Kriloha Gaskets, our manufacturing processes are grounded in international safety and quality standards. This ensures that every seal you install meets the rigorous demands of your specific industry.
Industry Applications
The Kriloha Advantage: Engineered Braiding Technology
At Kriloha Ltd., we don’t just “braid” yarn; we engineer a fluid barrier. Our manufacturing process utilizes Square-Interlock Braid technology, where every strand passes through the center of the packing. This creates a dense, dimensionally stable profile that resists “shredding” and ensures that lubricants—whether PTFE, Graphite, or Grease—are locked deep within the fiber matrix.
Vacuum Impregnation
We utilize a multi-stage vacuum process to ensure that individual fibers are "deep-soaked" in lubricants, creating a "Lubricant Reservoir".
Non-Abrasive Formulations
We prioritize "Shaft Safety." Our PAN and Kynol fibers are engineered to provide high-pressure containment without scoring stainless steel or bronze sleeves.
Thermal Agility
Our graphite-treated ranges act as a "thermal bridge," rapidly wicking heat away from the stuffing box to prevent packing "glazing."
Frequently Asked Questions (FAQ's)
Q: Why should I use Kynol® fiber instead of Aramid (Kevlar®)? While Aramid is incredibly
A: While Aramid is incredibly strong, it is highly abrasive and can quickly score or “cut” into metal pump shafts. Kynol fiber provides similar anti-extrusion strength but is much “softer” on the hardware, significantly extending the life of your expensive sleeves and shafts.
Q: What is the benefit of "Square-Interlock" braiding?
A: Standard “braid-over-braid” construction can delaminate or “unravel” under high pressure. Kriloha’s Square-Interlock braid ensures that all yarns are locked together through the core, resulting in a more stable packing that maintains its shape and seal throughout its service life.
Q: Does my packing need to leak to stay cool?
A: For most rotating applications, yes. A small, controlled leak-off (10-15 drops/min) acts as a coolant and lubricant. If the gland is tightened until all leaking stops, the packing will likely char or “glaze” the shaft, leading to catastrophic failure. Only specialized “zero-leak” valve packings should be tightened to a full stop.
Q: How does "Vacuum Impregnation" differ from surface coating?
A: Surface-coated packings lose their lubrication almost immediately as the pump starts. Kriloha’s Vacuum Impregnation forces the PTFE or Graphite into the microscopic pores of the fiber. This creates a “Reservoir Effect” where lubrication is slowly released as the packing wears, ensuring consistent performance for months, not days.
Q: Which fiber is best for seawater and marine stern glands?
A: Ramie is the premium choice for marine environments. It is the strongest natural fiber and is naturally resistant to rot, mildew, and bacteria. When impregnated with PTFE or Graphite, it provides a low-friction, high-strength seal that stands up to the corrosive nature of seawater better than flax or cotton.
Installation Best Practices
- Correct Sizing: Measure both the shaft diameter and the stuffing box ID. The cross-section must be precise to prevent “by-pass” leakage.
- Miter Cutting: Cut the packing into individual rings using a 45° miter joint for a perfect overlap.
- Staggered Joints: Always stagger the ring joints by 90° or 120° to prevent a “straight-line” leak path.
- Controlled Leak-Off: Unlike gaskets, most braided packings require a slight “leak-off” (approx. 10–12 drops per minute) to dissipate frictional heat and maintain lubrication.
