Is the HFC Series DN12.7 Quick-Connect Plug, BSPT Male with Valve, Polysulfone compatible with autoclaving and repeated sterilization cycles?

Yes. The HFC Series DN12.7 Quick-Connect Plug, BSPT Male with Valve, Polysulfone is compatible with autoclaving and repeated sterilization cycles. Constructed from robust polysulfone and rated for operating temperatures up to +138°C, it is explicitly described as suitable for autoclaving, offering chemical resistance and mechanical durability. Note that it uses an EPDM O-ring—while EPDM tolerates many sterilization processes, its longevity under repeated autoclave cycles can depend on cycle frequency, temperatures, and sterilant conditions; periodic inspection/replacement of the O-ring is recommended to ensure continued leak-free performance.

Can the HFC Series DN12.7 Quick-Connect Plug, BSPT Male with Valve, Polysulfone be used with aggressive chemical cleaners without degrading the EPDM seal or polysulfone body?

The HFC Series DN12.7 Quick-Connect Plug, BSPT Male with Valve, Polysulfone offers good chemical resistance overall: the polysulfone body is robust against many aggressive cleaners and the EPDM O‑ring provides strong resistance to a broad range of chemicals, mechanical stress, and temperature extremes (-40°C to +138°C). It is explicitly recommended for chemical processes and non‑freezing liquids and is autoclave‑compatible, indicating suitability for demanding, hygiene‑sensitive environments. However, compatibility is chemical‑specific. Some highly aggressive solvents, strong acids, ketones (e.g., acetone, MEK), chlorinated hydrocarbons, and certain concentrated bases can attack EPDM or polysulfone over time. For continuous exposure, high concentrations, elevated temperatures, or repeated cycling, material degradation and seal failure become more likely. Recommendation: confirm compatibility by checking the specific cleaner’s chemical compatibility with EPDM and polysulfone (supplier charts) or perform a soak/test under expected operating conditions (concentration, temperature, duration). If incompatibility is indicated, select alternative seal/materials (e.g., FKM, PTFE) or a coupling made from a more resistant polymer.

Additional information

Material	P – material (plastic)

The quick coupling plug with external BSPT thread and integrated shut-off valve is a lightweight yet highly durable solution designed for demanding water, chemical, and pneumatic systems. Unlike traditional heavy couplings with ball mechanisms and protective sleeves, its innovative construction ensures minimal weight while maintaining exceptional strength and reliability. The advanced valve system guarantees high flow capacity with virtually no leakage, while the ability to allow slight hose rotation prevents twisting and accidental disconnection, ensuring uninterrupted operation. Manufactured from robust polysulfone and equipped with an EPDM O-ring seal, the coupling offers outstanding resistance to chemicals and mechanical stress, making it ideal for use in chemical photographic processes, battery and accumulator filling systems, sprayers, pneumatic installations, and applications involving non-freezing liquids. Withstanding working pressures up to 8.6 bar and operating temperatures ranging from -40°C to +138°C, it is also suitable for autoclaving, ensuring safe and hygienic use in sensitive environments. Its compact design, high performance, and superior durability make it a reliable choice for professionals seeking efficiency, safety, and long-lasting quality in their installations.
