Products Description
Plate Heat Exchanger Rubber Seal Gasket is a core sealing component for plate heat exchangers. Installed in the groove of heat exchanger plates, it seals plate gaps, separates cold and hot media, and prevents internal cross-leakage and external liquid leakage. It ensures stable operation of internal flow channels and directly affects the operating efficiency, failure rate and service life of heat exchange equipment. Manufactured by the original factory with standardized processes, this gasket fits most mainstream plate heat exchanger models and meets sealing requirements for general and special working conditions.
Core Materials and Applicable Working Conditions
Nitrile Butadiene Rubber (NBR):
A cost-effective general-purpose material with excellent oil resistance, wear resistance and tear resistance. It works stably at -15℃ to 110℃, suitable for cooling water, mineral oil, vegetable oil and lye. It is widely used in HVAC water supply, industrial cooling and hydraulic oil heat exchange for long-term batch application.
Ethylene Propylene Diene Monomer (EPDM):
Features outstanding hydrolysis resistance and aging resistance. It adapts to aqueous media, normal-pressure steam and dilute acid-base solutions (pH 3-11) with a wider temperature range. Ideal for oil-free scenarios such as HVAC systems, domestic hot water, food-grade water heat exchange and chemical water treatment.
Hydrogenated Nitrile Butadiene Rubber (HNBR):
An upgraded version of NBR with enhanced temperature resistance, aging resistance and medium corrosion resistance. Its maximum working temperature reaches 150℃, applicable to sulfur-containing media, high-temperature oil and food-grade media for petrochemical, food processing and high-end industrial heat exchange equipment.

Applicable Industries and Equipment
This series of gaskets serves multiple industries including HVAC, municipal heating, food and beverage, pharmaceutical, petrochemical, water treatment, metallurgy, shipbuilding and machinery manufacturing. It is compatible with mainstream plate heat exchanger brands such as Alfa Laval, GEA and Accessen, suitable for routine replacement and batch supporting of both industrial continuous operation equipment and civil heating and water heat exchange equipment.
Industry-Specific Application Solutions
HVAC and Municipal Heating Industry:
Applied to plate heat exchangers for residential buildings, commercial complexes and municipal heat stations. Traditional gaskets easily age and relax under long-term warm water and intermittent steam conditions, causing water seepage, pressure loss, insufficient heating temperature and frequent equipment startup and shutdown. Our EPDM gaskets maintain stable resilience and hydrolysis resistance under such working conditions, eliminating heating season leakage failures, reducing manual maintenance frequency, ensuring 24-hour stable system operation and cutting operation costs of property and heating enterprises.
Food, Beverage and Pharmaceutical Industry:
Used for sealing of material cooling, purified water heat exchange and sterilization cooling plate heat exchangers. The core industry requirement is high medium cleanliness. Ordinary rubber gaskets easily precipitate impurities, peel off and mildew, causing medium cross-contamination and failing hygiene standards. Our food-grade gaskets feature pure material with no precipitation, tolerating conventional high-temperature sterilization and water washing. They ensure medium isolation, comply with industrial hygiene specifications and support continuous assembly line production.
FAQ
Q1: What is a Plate Heat Exchanger Rubber Seal Gasket used for?
A1: This core sealing part seals plate gaps, separates cold and hot media, avoids internal cross-leakage and external leakage, and ensures stable and efficient operation of plate heat exchangers.
Q2: How to choose the right gasket material for my working condition?
A2: Select materials based on medium, temperature and corrosion level. NBR for oil and general water; EPDM for water, steam and weak acid-base; HNBR for high-temperature oil and sulfur-containing media; FKM for strong corrosion and high temperature. We offer free professional selection guidance.
