Acrylic Fiber Gland Packing
PTFE-Impregnated Braided Sealing Solution for Pumps, Valves & Rotating Equipment
Product Overview
High-performance sealing packing manufactured from premium acrylic fiber yarns, tightly braided and fully impregnated with PTFE dispersion and inert lubricant. Designed to provide reliable, low-friction sealing for centrifugal pumps, valves, mixers, and rotating shafts. An excellent asbestos-free alternative for general industrial applications.
Key Advantages:
-
Excellent chemical resistance to weak acids, alkalis, oils, and solvents
-
Low coefficient of friction reduces shaft wear and power consumption
-
Uniform braided construction ensures consistent sealing pressure
-
Cost-effective replacement for PTFE or graphite packing in moderate service conditions
-
Wide range of sizes and custom configurations available

Centrifugal Pumps – clean water, slurry, chemical transfer
-
Mixers & Agitators – top-entry and side-entry mixing vessels
-
Valves – gate, globe, ball valves (static sealing)
-
Rotary Pumps – gear, lobe, screw pumps
-
Marine Equipment – stern tubes, rudder stocks, deck machinery
-
Paper & Pulp Industry – stock pumps, refiners, agitators
-
General Industrial Machinery – any rotating shaft requiring reliable packing
Why Choose Our Acrylic Fiber Packing?
1. Premium Braided Construction
Multi-strand acrylic yarns are tightly braided to achieve uniform density and cross-sectional integrity, ensuring stable sealing performance over long service intervals.
2. PTFE Impregnation
Each strand is fully saturated with PTFE dispersion and an inert lubricant, which reduces friction, minimizes shaft wear, and prevents hardening or shrinkage in service.
3. Chemical Resistance
Suitable for a wide pH range (3–11) and compatible with many industrial fluids, including water, oils, mild acids, and alkalis.
4. Cost-Effective Performance
Delivers an optimal balance between sealing efficiency and price, making it a preferred choice for general industrial sealing where exotic materials are unnecessary.
5. Customization & OEM/ODM
We offer custom sizes, special lubricants, color options, and private labeling to meet your specific market and branding requirements.

Frequently Asked Questions
Q: What is the lead time for bulk orders?
A: Standard sizes (6 mm – 25 mm) are typically in stock and ship within 3–7 working days. Custom sizes or special lubricants may require 7–15 working days. Expedited production is available for urgent projects.
Q: Can I get a free sample before placing a bulk order?
A: Yes, we provide free samples of our standard acrylic fiber gland packing for evaluation. Please provide your shipping address and required size. Samples are dispatched within 3–5 working days via DHL/FedEx/UPS.
Q: Do you offer OEM / private label services?
A: Absolutely. We provide full OEM/ODM services including custom packaging, private labeling, and tailored specifications. Our team will work with your branding guidelines to develop a product line that fits your market.
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 50 kg per size. For first-time customers, we can offer a trial order of 10–20 kg with slightly adjusted unit pricing. Contact our sales team for a customized quotation.
Q: How does acrylic fiber packing compare to PTFE or graphite packing?
A: Acrylic fiber packing offers an excellent cost-performance balance. It provides good chemical resistance and low friction at a more economical price point than pure PTFE packing. For demanding high-temperature or aggressive chemical applications, we recommend our PTFE or graphite series. Our engineers can help you select the optimal material.
