Is the Straight, through-hole plug connector, HP type 40040 compatible with polyurethane hoses of Shore A 98Â° and rated for 30 bar with Viton sealing?

Yes. The Straight, through-hole plug connector, HP type 40040 is compatible with polyurethane hoses of Shore A 98Â° and rated for 30 bar with Viton sealing. The product description explicitly states it is for polyurethane hoses with a minimum hardness of Shore A 98Â°, has a working pressure of 30 bar, and uses Viton sealing. Materials and operating temperature (nickel-plated brass; -15Â°C to +130Â°C) also support typical polyurethane hose applications.

Does the Straight, through-hole plug connector, HP type 40040 operate reliably between -15Â°C and +130Â°C with Viton sealing?

Yes. The Straight, through-hole plug connector, HP type 40040 specifies an operating temperature range of -15Â°C to +130Â°C and lists Viton sealing. Given Viton (FKM) is rated for continuous service roughly between -20Â°C and +200Â°C depending on formulation, the connectorâs Viton seal is compatible with and should operate reliably within the stated -15Â°C to +130Â°C range, assuming proper installation and that the specific Viton compound used meets expected chemical and pressure conditions (working pressure 30 bar).

Can Straight, through-hole plug connector, HP type 40040 be used with nickel-plated brass fittings in corrosive environments?

Straight, through-hole plug connector, HP type 40040 is made of nickel-plated brass, seals with Viton, and is specified for use with polyurethane hoses (minimum Shore A 98Â°), operating temperatures â15Â°C to +130Â°C, and working pressure up to 30 bar. Nickel-plated brass offers good general corrosion resistance, but its suitability in corrosive environments depends on the specific corrosive agents, concentration, temperature and exposure time. Brass can corrode in presence of ammonia, certain acids, chlorides (especially in alkaline or high-chloride environments), and hydrogen sulfide; nickel plating improves surface resistance and wear but is not equivalent to stainless steel or specialized corrosion-resistant alloys. Viton provides excellent chemical resistance to many oils, fuels, and some acids and solvents, and the polyurethane hose requirement (very hard, Shore A 98) indicates limited hose compatibility options. Conclusion: Straight, through-hole plug connector, HP type 40040 may be acceptable in mildly corrosive atmospheres (e.g., occasional moisture, light industrial fumes). It is not recommended for aggressive corrosive environments (strong acids, chlorides/saltwater, ammonia, hydrogen sulfide, or continuous chemical exposure) without additional verification. For aggressive or long-term corrosive exposure, choose connectors made from higher corrosion-resistant materials (e.g., stainless steel 316 or specialized alloys) and confirm compatibility of sealing material and hose. If needed, perform compatibility testing with the actual chemical conditions and operating temperature.
