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.

Used in:

Gate Valves

Globe Valves

Control Valves

Steam Valves

Graphite Gland Packing

✅ Features:

Withstands high temperatures up to 550°C

Resistant to chemicals, steam, and pressure

Flexible and easy to install

✅ Applications:

Steam valves

Power plants

Oil and gas pipelines

Chemical reactors

✅ Advantages:

Excellent thermal stability

High pressure resistance (up to 250 bar)

Cost-effective long-term sealing

PTFE Gland Packing

✅ Features:

Chemically inert and non-reactive

Temperature resistance up to 260°C

Low coefficient of friction

✅ Applications:

Globe and control valves

Acidic or alkaline chemical lines

Pharmaceutical and food-grade processing

✅ Advantages:

Ideal for corrosive environments

Non-stick, low wear

Prevents chemical contamination

Grafoil Gland Packing

Grafoil is a pure graphite-based material with no binders, making it perfect for nuclear and high-purity applications.

✅ Features:

Withstands extreme temperatures (up to 650°C)

High compressibility and resilience

Fire-safe and non-oxidizing

✅ Applications:

Nuclear plants

Superheated steam systems

Refineries and chemical plants

✅ Advantages:

Long-lasting under thermal cycling

Superior sealing under fluctuating pressure

Excellent in steam and high-purity services
