Description

This kit contains the primary “hard” valve seal (Part 9) and the corresponding high-tensile O-ring (Part 10) required to rebuild or service the valve assembly of the Daystate Pulsar. These components are manufactured to strict factory tolerances and use specific Shore-rated materials to withstand the high-pressure environment of a PCP rifle.

The Harper Slingshot Valve is central to the Pulsar’s efficiency, using a unique hammer design to eliminate “valve bounce” and air waste. Over years of use, the valve seat (Part 9) can develop micro-pitting or flat spots, which leads to “slow leaks” through the barrel or a drop in shot-to-shot consistency. Replacing these parts restores the rifle’s airtight integrity and return-to-zero performance.
