DLS 10mm Straight Connector (3/4″ B.S.P) Blue c/w Nut and Washer

The DLS 10 mm Straight Connector ¾″ B.S.P (Blue) is a reliable plumbing adaptor fitting designed for use in caravans, motorhomes, campervans and boats where a compact and direct connection between 10 mm water pipe and a ¾″ B.S.P threaded outlet is required. Finished in distinctive blue and supplied with a C-nut and sealing washer, this straight connector makes it simple to join standard water pipework to threaded hose points, external taps or service panel outlets in fresh water systems.

Because many leisure vehicle plumbing installations involve transitions between rigid pipework and external threaded outlets, this connector provides a tidy, secure and leak-resistant link that supports everyday water use — from filling tanks to supplying outdoor taps.

How and Where It Is Used

The DLS 10 mm Straight Connector is used in the fresh water delivery system of leisure vehicles wherever there’s a need to transition from 10 mm water pipework to a ¾″ threaded outlet — commonly found on external hose points, tap connectors or fill points. The straight design means it aligns directly without changing pipe direction, making it ideal when clearance and routing allow a straight join.

Common locations and uses include:

• External water outlets: Linking internal pipework to an exterior garden-style hose point or utility tap

• Service panel connections: Joining fresh water lines to tap or fill connections behind service ports

• Internal plumbing: Joining pipework to internal taps or quick-release outlet points

• Deck shower or rinsing outlet: Providing threaded attachment for flexible hoses

• Retrofit upgrades: Replacing old or worn connectors in existing systems

The protective C-nut and washer supplied with the fitting form a watertight joint when tightened onto the corresponding ¾″ male thread, ensuring a secure connection that resists leaks under pressure.

Uses

• Transitioning 10 mm fresh water pipe to ¾″ threaded outlets

• Plumbing external taps or hose points on caravans & motorhomes

• Quick installation in service panels or utility outlets

• Supplying water for outdoor rinse hoses or showers

• Repairing or upgrading water system connections

Fitting Instructions

1. Turn off & depressurise water: Before working on any water line, shut off the fresh water supply and relieve pressure in the system.

2. Prepare the pipe end: Using a proper pipe cutter, cut the 10 mm pipe squarely and deburr the edge so it’s smooth and clean.

3. Slide on the C-nut: Slip the blue C-nut onto the pipe, followed by the sealing washer so it sits against the face of the nut.

4. Fit the connector: Push the straight connector into the pipe end until fully seated.

5. Engage the B.S.P thread: Align the connector’s ¾″ B.S.P male thread with your outlet or fitting and hand-thread the nut onto the matching female port.

6. Tighten the nut: Using a suitable wrench, tighten the C-nut to compress the washer and create a secure, leak-resistant seal. Do not overtighten — a snug fit is sufficient.

7. Check & flush: Turn the water supply back on slowly, check for leaks around the joint, and flush water through to ensure proper flow.

Tip: Applying a small bead of food-grade silicone grease to the sealing washer can help ensure a better seal and make future removal easier without damaging the washer.
