Description

Overview

Water Tank Tap 20mm BSP gives a simple shut-off point at a tank outlet, so you can control draining or dispensing without cracking a hose clamp. The 20mm BSP thread size helps you match common fittings used on truck and trailer water tanks. Because tank plumbing varies, confirm your outlet thread and sealing method before you order.

This tap suits straightforward water tank setups where you want a basic on or off function, and it also helps during servicing when you need to isolate a line.

Features

• 20mm BSP threaded connection for tank outlet fitment
• Simple manual tap function for controlled flow
• Compact part that suits tight mounting spaces
• Ideal as a replacement tap on compatible water tanks

Specifications and Materials

This Water Tank Tap 20mm BSP uses a 20mm BSP thread size for fitment.

Use the tap as a tank outlet control point for draining, filling transfer lines, or dispensing water when the system allows.

Part number: CA7705.

See ISO 228 thread standard overview for background on BSP parallel threads used on fittings and taps.

Compatibility and Fitment

Match the 20mm BSP thread to the tank outlet or adaptor you already use, otherwise the tap will not seal correctly. If your setup relies on a gasketed face seal, make sure the mating surfaces sit flat, then tighten the connection evenly. When you add a hose tail or adaptor, keep the load off the tap body so vibration does not loosen joints over time.

Before first use, cycle the handle a few times, then check for seepage under light flow because small leaks usually show up early.

Compliance and Safety

Install the tap so it cannot be struck by road debris, and protect it if the tank sits low. Also route hoses so they do not rub, because chafing can lead to sudden leaks. If you use the tank for drinking water, choose seals and downstream fittings that suit that purpose and follow your maintenance routine.

Trailer Applications

Water Tank Tap 20mm BSP suits water tank systems fitted to trailers, service bodies, and equipment where a basic outlet tap makes draining easier. It also suits replacement work when a tap has seized, cracked, or started to weep, provided the thread size matches.
