Is the Connector with BSP Female Thread and Corrugated Tail Shell Clamp, Type MSLR suitable for continuous operation at 25 bar and within -20°C to +65°C?

Yes. The Connector with BSP Female Thread and Corrugated Tail Shell Clamp, Type MSLR is specified for continuous operation at up to 25 bar and within the temperature range −20°C to +65°C. It is designed to EN 14420-3 / DIN 2817 standards, offers durable hose connection with a corrugated tail, and comes in brass (MS) or stainless steel 316 (SS) with appropriate gaskets (polyurethane for brass, PTFE for SS) to ensure reliable performance and tightness under those conditions.

Can the Connector with BSP Female Thread and Corrugated Tail Shell Clamp, Type MSLR be used with aggressive chemicals or abrasive media without compromising its gasket and material integrity?

Connector with BSP Female Thread and Corrugated Tail Shell Clamp, Type MSLR can handle many demanding industrial fluids, but suitability with aggressive chemicals or highly abrasive media depends on selected materials and gasket type. Key points: - Material choice: Stainless steel 316 versions offer substantially better corrosion resistance to many aggressive chemicals than brass (MS). For strongly corrosive media, SS316 is the preferred option; brass may degrade with acids, chlorides or other aggressive agents. - Gasket compatibility: Standard flat gaskets are polyurethane for brass and PTFE for stainless steel. PTFE provides excellent chemical resistance across a wide range of aggressive solvents, acids and alkalis; polyurethane is less resistant to strong chemicals and may swell or degrade with certain solvents. - Abrasive media: Neither version is specifically hardened against heavy abrasion; abrasive solids in the fluid can wear the corrugated tail and sealing surfaces over time. Stainless steel resists wear better than brass, but high-solid or highly abrasive slurries will shorten service life and may compromise seal integrity. - Temperature/pressure limits: Designed for up to 25 bar and -20°C to +65°C. Chemical compatibility must be evaluated within these limits; elevated temperatures can accelerate chemical attack or gasket failure. Recommendation: For aggressive chemicals choose the SS316 with PTFE gasket and verify chemical compatibility against the specific media and operating temperature. For abrasive slurries consider hardened or abrasion-resistant alternatives, additional filtration, or more frequent inspection/replacement.
