Rain Bird SPB-025 adapter from PE tubing to micro tubing - pack of 10

Adapter from PE tubing to micro tubing

The Rain Bird SPB-025 connector provides a simple transition from larger PE distribution tubing to ¼" micro tubing. Its self-piercing inlet barb is inserted directly into suitable ½" or ¾" distribution tubing, while the opposite barb accepts ¼" distribution tubing such as Rain Bird XQ 4/6 mm micro tubing.

This pack contains 10 SPB-025 connectors, allowing multiple branches to be created within a micro irrigation system. Individual micro tubes can be routed from the larger distribution line to drip emitters, micro-sprays or other watering points.

Self-piercing connection for PE tubing

The inlet side of the SPB-025 features a self-piercing barb that is inserted directly into the wall of suitable ½" or ¾" distribution tubing. No additional threaded fitting or adhesive is required for this connection.

Rain Bird recommends the XM-TOOL Xeriman installation tool for quick and convenient installation. It makes inserting the self-piercing connector into the distribution tubing easier, particularly when installing micro irrigation systems with multiple branches.

Connection for 4/6 mm micro tubing

The outlet of the SPB-025 is designed for Rain Bird ¼" XQ distribution tubing. Compatible tubing includes Rain Bird XQ-100 and XQ-1000. With approximately 4.3 mm inside diameter and 6.3 mm outside diameter, this tubing is commonly referred to as 4/6 mm micro tubing.

The grey outlet of the SPB-025 indicates unrestricted flow. The connector is therefore not a drip emitter and does not provide a fixed flow rate. The required water output is determined by the drip emitter, micro-spray or other emission device installed downstream.

Flexible branches for micro irrigation

The SPB-025 allows individual micro tubes to be routed from a larger distribution line directly to plants. This is useful for flower beds, shrubs, hedges, trees and container plants when the individual watering points are not located directly beside the main distribution tubing.

Its compact construction allows the adapters to be integrated discreetly into an irrigation system. The rugged plastic construction is designed for irrigation applications, and Rain Bird specifies an operating pressure range of 0 to 3.5 bar.

Frequently asked questions about the SPB-025

What is the Rain Bird SPB-025 used for?

The SPB-025 creates a branch from ½" or ¾" distribution tubing to ¼" distribution tubing or compatible micro tubing. This allows individual watering points to be supplied from a larger distribution line.

Is Rain Bird XQ 4/6 mm micro tubing compatible?

Yes. The SPB-025 outlet is designed for Rain Bird ¼" XQ distribution tubing, including XQ-100 and XQ-1000 with approximately 4.3 mm inside diameter and 6.3 mm outside diameter.

Does the SPB-025 restrict the water flow?

No. The SPB-025 is a connector rather than a drip emitter or flow regulator. Its grey outlet indicates unrestricted flow. The final water output is determined by the downstream emission device.

How is the SPB-025 installed?

The self-piercing inlet barb is inserted directly into suitable ½" or ¾" distribution tubing. The Rain Bird XM-TOOL Xeriman installation tool makes installation particularly quick and convenient.

What is the maximum operating pressure?

Rain Bird specifies an operating pressure range of 0 to 3.5 bar for the SPB-025.

Is glue or a threaded fitting required?

No. The SPB-025 uses barb connections and does not require adhesive or threaded fittings for its intended installation.
