For tank farm engineers, digester operators, and inspection planners, the Shand & Jurs 95210 Clamping Manway Cover provides secure, gas-tight, and watertight personnel access to low-pressure storage tanks, digesters, and process vessels, combining frequent inspection access with consistent vapor containment.
Unlike unsealed manway covers that rely on gasket compression from a full bolt pattern and drift toward leakage as bolts loosen or seals age, the 95210 uses a threaded clamping mechanism that applies uniform compression to a flexible elastomer seal, maintaining reliable closure at approximately 1–3 PSIG working pressure.
A hinged cover configuration allows rapid, unobstructed access for inspection and maintenance without removing the cover from the tank. Optional non-ferrous clamping hardware in bronze, brass, or stainless steel provides spark-resistant performance in flammable product service.
Available in 16″ through 48″ sizes with flat-face drilled flanges to ANSI, API, or EN standards, the 95210 integrates with common tank nozzle configurations and supports petroleum, chemical, and industrial storage where secure closure and personnel access must coexist.
Provides uniform seal compression for gas-tight and watertight closure, avoiding the loosening and drift that bolt-pattern covers develop over service life.
Enables rapid, unobstructed access for inspection and maintenance without removing the cover from the tank during routine service events.
Maintains consistent compression and reseating performance under low internal pressures, delivering stable containment across repeated open-close cycles.
Sizes from 16″ to 48″ accommodate standard tank and vessel manway openings across petroleum, chemical, and digester storage architectures.
Supports ANSI, API, or EN bolt patterns, giving installation flexibility across regional tank-construction standards without custom nozzle adaptation.
Bronze, brass, or stainless clamping hardware reduces spark risk in hazardous environments where flammable vapor and metallic impact could otherwise coincide.

A bolted manway cover depends on the full bolt pattern applying even gasket compression, and both the bolt torque and the gasket drift over repeated open-close cycles. The 95210 uses a threaded clamping mechanism that applies uniform compression to a flexible elastomer seal, maintaining consistent gas-tight and watertight closure across inspection cycles without the drift of a multi-bolt pattern.
Standard working pressure capability ranges from approximately 1 to 3 PSIG depending on size, supporting low-pressure storage tanks, digesters, and process vessels where secure closure and personnel access must coexist.
The 95210 is offered in 16″, 18″, 20″, 24″, 30″, 36″, 42″, and 48″ nominal diameters with flat-face drilled flanges to ANSI, API, or EN standards. An undrilled flange version is available for custom bolt patterns where a project specification requires non-standard drilling.
Yes. Non-ferrous clamping hardware in bronze, brass, or stainless steel is available to reduce spark risk in flammable vapor environments, and an ATEX configuration is available for hazardous area applications where the site classification requires it.
Bodies are offered in aluminum, carbon steel, or 316 stainless steel. Seals are available in NBR (nitrile) or CR (chloroprene) for product compatibility. Temperature capability is seal-dependent and typically covers roughly −20°F to 250°F; specify stored product and service conditions at time of order.
Installation is on existing manway nozzles where personnel entry and inspection access are required — storage tank roofs and shells, digester tops, floating roof access ports, and low-pressure process vessels. Flat-face drilled flanges match common ANSI, API, and EN nozzle patterns.
With over a century of tank-safety heritage inside Cognesense, the Shand & Jurs 95210 Clamping Manway Cover is chosen when low-pressure tanks, digesters, and process vessels require frequent inspection access without giving up vapor or weather-tight closure. Its threaded clamping mechanism, flexible elastomer seal, and hinged cover configuration maintain consistent gas-tight and watertight sealing across repeated open-close cycles. For petroleum, chemical, and industrial storage, the 95210 is trusted wherever you need to measure, monitor, and protect what matters most.
