Everis BLQ4 non-spill blind mate coupling insert, G1/4 male thread (BSPP), chrome-plated brass, EPDM - CPC BLQ4D47004

BLQ4D47004 is the insert half of the Everis BLQ4 blind mate coupling, with 1/4" flow size and a G1/4 male thread. Its valve closes so tightly that CPC specifies spillage below 0.025 cc at 0 psi and below 0.055 cc at 120 psi per disconnect. Operating pressure ranges from vacuum up to 8.3 bar.

Use in the data center

• Blind mate connection: the insert engages its mating body as the server sled slides into the rack, with no hand access to the coupling required.
• Direct-to-chip cooling: links the cold plate loop inside the sled to the rack manifold.
• Service while running: sleds can be pulled and swapped under pressure without drips, and the cooling loop does not have to be drained.
• Long-term connected use: according to CPC, the friction-free valve is designed to stay connected for extended periods.

Benefits

• Drip-free disconnect under pressure: less than 0.055 cc spillage per disconnect at 120 psi (8.3 bar), and inclusion below 0.025 cc per connect.
• Redundant seals: a second sealing barrier adds protection against leaks near sensitive electronics.
• Engagement tolerance: axial tolerance keeps full flow available even when the insert is not seated to the exact stroke.
• Made for repeated cycling: chrome-plated brass housing and a stainless steel valve spring for long-term, repeated use.
• Wide temperature range: -17 to 115 °C with EPDM seal.
