An exemplary fire suppression sprinkler includes a housing (22) that establishes a flow path for discharging fire suppression fluid. A water seat (28) is configured to block the flow path. A polymer seal (30) is supported within the housing (22) and engages the water seat (28) for sealing an interface between the flow path and the water seat (28). A spring member (40) biases the polymer seal (30) into engagement with the water seat (28).

A tool for draining a fire sprinkler system through a fire sprinkler, comprising: a housing configured for cooperation with the sprinkler to collect fluid flowing from the sprinkler; an actuator to activate the sprinkler; and a conduit in fluid communication with the housing 5 and through which the fluid can be drained.

A fire suppression system comprising a polymer housing and an internal channel arranged to communicate a fluid from a fluid inlet to a fluid outlet. The fluid outlet is in the form of at least one aperture extending through a portion of the polymer housing into said channel.

A concealable sprinkler head includes a frame having a body mountable to a fire suppression liquid source, a pair of frame arms and a pair of corresponding drop pins slidably engaged with a respective frame arm. A thermal trigger is supported within the sprinkler frame. A fluid deflector is secured to the drop pins and includes a generally horizontal surface. The drop pins extend substantially orthogonally from the horizontal surface. An inclined surface of the fluid deflector extends angularly upwardly from the horizontal surface. A concealing cup surrounds the frame arms. A cover plate is attached to the concealing cup, covering the distal end thereof, wherein the drop pins and the deflector are positioned within the concealing cup. The cover plate is removable from the concealing cup permitting the drop pins and the deflector to axially slide out of the concealing cup into an operational position.

A tire protection sprinkler including a frame body having an inlet, an outlet, defining an internal passageway extending between the inlet and the outlet along a sprinkler axis. A dome shaped deflector member is centered, axially aligned with the sprinkler axis, and spaced from the outlet. The deflector member has an outer surface and an inner surface that preferably includes: a peripheral region, a central region and an intermediate region. The intermediate region includes a primary deflecting surface, and a secondary deflecting surface that is surrounded by the primary deflecting surface The deflector member provides for generation of a non-circular spray pattern defined by four zones of fluid density concentrically formed about the sprinkler axis.
