FAQ
Q1: Is this S7A gasket a direct replacement for original S7A refrigeration heat exchanger?
A: Yes. Our S7A heat exchanger gasket is precisely produced according to OEM original size, sealing profile and groove position, direct plug-and-play replacement without cutting, drilling or modification.
Q2: What material options are available for S7A refrigeration gaskets?
A: We provide refrigeration grade NBR (for oil-containing refrigerants) and refrigeration grade EPDM (for water/glycol, common cooling media). Our team can recommend the best material according to your refrigeration medium.
Q3: Why special refrigeration gaskets instead of ordinary rubber gaskets?
A: Ordinary gaskets are easy to harden, crack or swell in low temperature & refrigerant environment. Our dedicated refrigeration formula ensures low-temperature flexibility, anti-refrigerant corrosion and long service life, avoiding frequent shutdown maintenance.
Q4: Can your S7A gasket resist low-temperature refrigeration working conditions?
A: Absolutely. Custom low-temperature resistant formula is designed for refrigeration & cooling systems, keeping good elasticity and sealing performance without brittle cracking in long-term cold operation.
Q5: How long is the service life of the S7A refrigeration heat exchanger gasket?
A: Under standard refrigeration working conditions, the service life is 3–5 years, 40% longer than ordinary mixed rubber gaskets. Regular cleaning and inspection can further extend usage time.
Q6: What is your MOQ and delivery time?
A: Standard MOQ is 10 sets; small trial order of 5 sets is acceptable. Stock specifications can be shipped in 5–7 working days, customized material gaskets take 10–15 working days.
Q7: Do you support customized size, color or OEM packaging?
A: Yes. We support custom thickness, color, logo printing and OEM branded packaging to meet your distribution and project customization demands.
