An UltraZap 40mm complete union (1½ inch) is a serviceable PVC pipe connector that unscrews whenever you need to take something out of the line — no cutting and regluing. Put one on each side of a pump, filter or other equipment in a pond, aquarium or fish tank plumbing run, and lifting that item out for servicing becomes a job of minutes, not an hour.

Good to know:
– 40mm size, 1½ inch union
– Comes apart without cutting the pipe
– Ideal in-line at pumps, filters and other serviceable gear
– For pond, aquarium and fish tank PVC plumbing
