Also known as chevron packing seals, our Vee‑Packing sets adopt multi‑layer stacked V‑lip self‑energizing sealing structure. Sealing force rises automatically along with system pressure, delivering reliable dynamic sealing for reciprocating piston and rod of single‑acting & double‑acting hydraulic and pneumatic cylinders.

We supply standard‑size Vee packing and support fully custom manufacture per drawings or samples. Multiple material options: rubber(NBR/FKM/EPDM), PTFE, nylon, Kevlar fabric‑reinforced compound. Suited for hydraulic cylinders, industrial pumps, valves and heavy‑duty machinery. Factory direct wholesale for global manufacturers, repair workshops and engineering contractors.

Main Material Options

✅ Rubber Vee Packing

Cost‑effective general‑purpose chevron seals made from premium NBR, FKM, EPDM. Good elasticity, compression recovery and wear resistance. Stable sealing under medium‑pressure & normal‑temperature conditions, resist oil, water and common industrial media. Easy for installation & replacement. Widely used for routine maintenance of general industrial cylinders, pumps and valves.

✅ PTFE Vee Packing

High‑end corrosion‑resistant solution for harsh chemical working conditions. Made of pure or modified PTFE; outstanding chemical inertness, low friction coefficient, wide temperature adaptability. Resist strong acid, alkali and organic solvent, no aging or deformation under alternating hot‑cold cycles. Ideal for chemical, pharmaceutical, food‑processing and precision hydraulic equipment where ordinary rubber seals fail.

✅ Fabric‑Reinforced Vee Packing (Kevlar Reinforced)

Heavy‑duty ultra‑high‑pressure sealing for extreme working conditions. Reinforced by high‑strength Kevlar / industrial woven fabric, greatly improved tensile strength, anti‑extrusion property and pressure resistance, max working pressure up to 40 MPa. Prevent seal blow‑out under heavy load. Excellent wear‑resistance & anti‑fatigue performance. Preferred for large hydraulic cylinders, heavy machinery, engineering equipment and high‑pressure pump systems.

FAQ about vee packing seals:

Q1: What is Vee Packing used for? A: Vee Packing, also known as chevron packing, is a multi-lip dynamic sealing component mainly used for reciprocating motion sealing of hydraulic cylinders, pneumatic cylinders, industrial pumps and valve equipment. It is suitable for medium and high pressure working environments, providing reliable leakage prevention protection for various industrial mechanical dynamic systems.

Q2: What are the advantages of Vee Packing seals? A: Vee packing features adaptive pressure sealing, strong pressure resistance, good wear resistance and long service life. The stacked structure can be freely combined according to working conditions, supporting customized size and material matching. It has strong environmental adaptability and can meet the sealing needs of conventional and extreme industrial scenarios.

Q3: Which material is best for Vee Packing? A: Rubber is suitable for conventional medium-pressure and normal-temperature scenarios; PTFE is ideal for corrosion-resistant and high-precision scenarios; fabric reinforced material is the best choice for ultra-high pressure and heavy-duty working conditions. We can recommend the most suitable material solution according to your actual working pressure, temperature and medium environment.

Q4: Can you provide custom Vee Packing? A: Yes. We support full customization of Vee Packing, including custom outer diameter, inner diameter, height, number of sealing rings and special material formula. Both standard size wholesale and non-standard OEM processing are available to meet diverse equipment matching needs.
