Extremo de tope a presión de 28 mm de Alien Hydroponics

Precision Control in Any Space

Every unused port in a live irrigation circuit is a liability. When a line termination point is not properly sealed — whether it is a capped branch on a top-feed manifold or an idle outlet on a drain-to-waste header — the result is not neutral. Pressure bleeds. Nutrient solution wicks. Residual moisture accumulates at the fitting interface and becomes a vector for contamination between runs. The enemy is not a catastrophic failure; it is the slow, invisible cost of fittings that were never designed to work together, improvised solutions that hold until they do not, and the run-to-run variance that follows when your irrigation circuit is not fully closed.

After proper termination with a system-matched stop end, the circuit behaves as designed. Every active feed line delivers its programmed volume. Unused ports contribute nothing — no drip, no pressure loss, no contamination pathway. Between runs, the manifold flushes clean because there are no improvised caps trapping residual solution in dead-end pockets. The operator gains confidence that what the controller schedules is what the root zone receives, run after run, without manual inspection of every termination point before lights-on.

The 28mm Push-Fit Stop End achieves this through direct mechanical compatibility with the Alien Hydroponics V-SYSTEM platform. The push-fit engagement mechanism is sized and toleranced to the V-SYSTEM's 28mm port specification, meaning the fitting seats fully on insertion without tools, thread tape, or secondary sealing compounds. Compatibility is not approximate — it is manufacturer-matched. The stop end terminates the line at the port, not downstream of it, eliminating the dead-leg volume that accumulates in non-flush termination designs. In practical terms, the 28mm Push-Fit Stop End delivers a fully sealed, pressure-stable termination at any unused V-SYSTEM port for $9.20 per fitting with no additional sealing materials required.

Where This Belongs (and Doesn't)

This fitting is a plumbing component rated for low-pressure irrigation service within the Alien Hydroponics V-SYSTEM. It is not rated for pressurized mains, potable water supply lines, or any application outside the V-SYSTEM platform. Do not use as a substitute for pressure-rated fittings in non-irrigation circuits.

How It Works

The push-fit mechanism operates on a collet-and-seal principle standard to professional irrigation fittings. When the stop end is inserted into a V-SYSTEM 28mm port, an internal collet ring grips the port wall and an elastomeric seal compresses against the bore to create a leak-free closure. No tools are required for installation. Removal, where the fitting design permits, is achieved by depressing the collet release collar and withdrawing the fitting — allowing the operator to reconfigure the circuit without cutting tubing or replacing fittings.

Because the stop end is manufacturer-matched to the V-SYSTEM's 28mm port geometry, the collet engagement depth and seal compression are within the tolerances Alien Hydroponics specifies for leak-free performance. Off-system fittings introduce dimensional variance at the collet interface that can result in incomplete seating, reduced grip force, and seal bypass under operating pressure. System-matched termination eliminates that variable entirely. In practical terms, the 28mm Push-Fit Stop End installs in seconds at any unused V-SYSTEM port and holds a leak-free seal under normal irrigation operating pressures without supplemental sealing materials.

Commercial Assurance

• Manufacturer Compatibility: Factory-specified for Alien Hydroponics V-SYSTEM 28mm ports — not a generic fitting adapted to fit.
• Authorized Distribution: Sold through Cannafull Spectrum Solutions as a factory-authorized dealer. Authenticity is guaranteed at point of sale.
• Warranty: Warranty terms are not specified in available source data. Contact Cannafull Spectrum Solutions at cannafullspec.com for current warranty information before ordering.
• Local Availability: Available for in-person pickup at our Longmont location — no shipping lead time for local operators.
• Flexible Payment: Available in 4 payments of $2.30 USD via Sezzle for qualifying orders.

System Integration

• V-SYSTEM Manifold Compatibility: Seats directly into any 28mm V-SYSTEM port without adapters, thread tape, or secondary sealants.
• Top-Feed Circuit Integrity: Eliminates pressure bleed at unused manifold outlets, ensuring programmed feed volumes reach only active zones.
• Drain-to-Waste Reservoir Systems: Caps idle branch lines between runs to prevent residual solution accumulation and cross-contamination.
• Flush and Sanitation Cycles: Allows operators to isolate and seal inactive circuit segments during between-run cleaning without disassembling the manifold.
• Scalable Deployment: Priced at $9.20 per unit, making it practical to stock multiples for full-circuit termination across multi-zone V-SYSTEM installations.

Facility Integration Data

For operators managing multi-zone V-SYSTEM installations, the per-unit cost of proper termination is negligible relative to the feed variance and contamination risk introduced by unmatched or improvised stop ends — the table below illustrates total termination cost at scale.

Operator Field Notes

• Stock multiples before you need them: At $9.20 per unit, running short of stop ends mid-reconfiguration is an avoidable delay — keep a working inventory on hand for any V-SYSTEM installation with more ports than active feed lines.
• Inspect the port before insertion: Push-fit seals require a clean, undamaged port bore. Debris or deformation at the port rim will compromise collet engagement and seal compression — wipe ports clean before fitting installation.
• Do not force a non-seating fitting: A properly matched 28mm stop end seats with firm hand pressure. Resistance before full engagement indicates a port obstruction or dimensional mismatch — do not force the fitting or use tools to drive it home.
• Verify seal integrity before pressurizing: After installing stop ends on any reconfigured circuit segment, run a low-pressure check before returning to full operating pressure. A visual inspection at each termination point takes less than a minute and confirms seal engagement.
• Local pickup eliminates lead time: For operators in the Longmont area, in-person pickup means same-day availability — no waiting on shipping when a run is scheduled and a fitting is needed.
