Premium Pure Black UPVC End Caps (Slip Socket)

Secure the termination points of your fluid network while maintaining a flawless, algae-free system with our Heavy-Duty Pure Black UPVC End Caps. The dead end of a pipeline is vulnerable to both hydraulic shock and, in clear or light-colored PVC, unsightly algae buildup. Featuring a sleek, high-gloss black finish, these caps provide 100% light-blocking protection. Rated for high-pressure industrial use (1.6 MPa), they deliver a rock-solid, blowout-proof seal, making them the ultimate choice for high-end reef aquariums, professional hydroponics, and purified water setups.

🌟 Key Engineering Features:

Algae-Proof Aesthetic: The solid black construction completely blocks light penetration, preventing internal bio-fouling and keeping your water pristine, all while giving your exposed plumbing a highly professional look.

Blowout-Proof Design: Engineered with a reinforced end face to absorb severe pressure spikes and water hammer at the end of the line, preventing hairline fractures and catastrophic leaks.

Industrial Chemical Resistance: Molded from non-toxic, unplasticized PVC. Highly resistant to corrosive wastewater, strong acids, alkalis, and marine saltwater.

Permanent Slip Connection: Features a perfectly machined internal slip socket (measured by Inner Diameter - ID) designed for a seamless, permanent solvent weld (glue) connection that effectively becomes one with the pipe.
