Graphite, PTFE & Grafoil Gland Packing for Gate, Globe & Control Valves
Valves play a critical role in controlling fluid flow, and gland packing ensures they remain leak-proof even under extreme pressure and temperature. Among the most trusted sealing materials are Graphite, PTFE (Teflon), and Grafoil – each with specific advantages tailored for different valve types and industrial conditions.
At Udhhyog, Delhi’s top gland packing supplier and valve manufacturer, we provide high-performance sealing solutions for gate, globe, and control valves, serving industries like steam, chemical, water treatment, and power generation.
This article breaks down the properties and applications of graphite, PTFE, and Grafoil gland packing and provides specifications for their ideal use in valves.
What is Gland Packing?
Gland packing is a sealing material inserted around the valve stem inside a chamber known as the stuffing box. It prevents leakage by forming a tight seal when compressed using a gland follower and gland flange.

Gland Packing in Valves – Types, Materials, and Specifications Explained
Gland packing is one of the most critical components used in valves to ensure sealing between the valve stem and the bonnet. Whether in steam, gas, or chemical applications, proper gland packing prevents leakage, enhances valve life, and ensures safety and efficiency in pipeline systems.
As a reputed valve and gland packing supplier in Delhi, Udhhyog offers a wide variety of gland valve types, packing materials, and solutions tailored to industrial needs.
This article provides a complete overview of what gland packing is, the types of materials used, application-specific specifications, and valve compatibility.
What is a Valve Used For?
Valves are mechanical devices used to control, regulate, or shut off flow in piping systems. They are used in:
Oil & Gas Pipelines
Steam Systems
Water Treatment Plants
Chemical Processing
HVAC Systems
Valves like gate, globe, ball, and control valves rely heavily on gland packing to ensure leak-proof stem operation.
What is Gland Packing in Valves?
Gland packing is a sealing material compressed between the valve stem and bonnet through a gland follower and gland flange. It prevents media leakage along the stem, especially under pressure and temperature.
Common in:
Gate Valves
Globe Valves
Ball Valves
Control Valves
Steam Valves
Gland Valve Anatomy
Key components:
Gland – The upper compression ring
Gland Flange – Holds the gland in place
Packing Rings – Made of PTFE, graphite, asbestos-free yarns, etc.
Stuffing Box – Chamber where packing is placed
Gland Follower – Compresses packing uniformly
Types of Gland Packing Materials

Graphite/PTFE hybrids recommended
🔸 Ball Valve Gland Packing
Found in stem sealing areas
PTFE preferred for low-torque rotation
🔸 Control Valve Gland Packing
Needs flexible, low-friction, chemically inert materials
PTFE or expanded graphite
🔸 Steam Valve Gland Packing
Must withstand high temperature and thermal cycling
Use graphite or Spitmaan graphite gland packing
Gland Packing for Steam Valves
Steam valves operate under extreme temperatures and pressure, and leakage can cause energy loss and hazards. Preferred materials include:
Flexible graphite
Carbon-impregnated PTFE
High-temperature Spitmaan yarns
Installation requires:
Proper ring stacking
Uniform compression
Avoiding over-tightening (can damage stem)
