4‘’ TC cap with gas post and PRV

Pressure, sorted — big-port edition.

A 4" tri-clamp cap with a built-in gas post and pressure relief valve. Pressurise or purge through the gas post, and let the PRV vent automatically if pressure climbs too high (around ±4 PSI tolerance). Ideal for closing and pressurising a 4" lid port.

Key points

• Gas post — pressurise or purge with CO₂
• Built-in PRV (~±4 PSI tolerance)
• 4" tri-clamp connection
• 304 stainless, sanitary

Note: ships without a 4" band clamp — add one separately.
