VESDA E700-SP — miniature sampling point for aspirating smoke detection (ASD) systems, for 8 mm OD capillary tube.
In an aspirating system the detector draws air through a network of pipe. The sampling point is what creates a defined, visible air inlet at the end of a capillary run, so air is drawn from the exact location that needs protecting rather than from the general pipe route. The E700-SP is a conical surface-mount fitting designed as the termination for an 8 mm capillary tube.
Installation is push-in: the tube pushes into the fitting and a built-in locking ring holds it and maintains airflow integrity, which matters because a loose capillary changes the airflow balance of the whole pipe network. The injection-moulded engineered polymer body is corrosion resistant for long service life.

Companion part: the matching capillary tube is the E700-CT, 5.2 mm ID / 8 mm OD, sold per metre. The E700-CAPKIT plastic connector kit is used where the capillary joins the trunk pipe.
Design note: the length of each capillary tube is a critical element of the VESDA ASPIRE calculation and should be kept to a minimum wherever possible for optimum performance. Run the pipe network through ASPIRE before committing to capillary lengths — a long capillary can put transport time outside the listed limit even when the rest of the network is correct.
Typical applications are data halls, cleanrooms, communications and equipment enclosures, and high-ceiling spaces where a discreet, precisely placed inlet is needed.
