Boshart 14A-MBS-03 L-Style Zinc-Plated Mounting Bracket

The Boshart 14A-MBS-03 is an L-style zinc-plated mounting bracket supplied complete with hardware, designed to secure a point-of-use filter housing to a wall, cabinet, or under-sink cavity during rough-in installation. This bracket ships as part of a filtration kit that also includes a white polypropylene filter bowl, a black polypropylene filter head with a pressure-relief button, two 1/2" MPT x 3/8" compression adapter fittings, a full circle filter wrench, and an AS568-237 NBR O-ring plus one extra replacement O-ring. The mounting bracket itself is the structural component plumbers and installers rely on to hold the filter assembly firmly in place, keeping the compression fittings and filter head properly aligned to the incoming and outgoing 3/8" supply lines. Built to a no-lead standard, this kit is intended for potable point-of-use water applications where a securely anchored filter housing is required.

Key Features

  • L-Style Design: The bracket's L-shaped profile allows the filter housing to be mounted flush against a wall or cabinet panel, keeping the assembly stable and out of the way in tight under-sink or point-of-use installations.
  • Zinc-Plated Construction: Zinc-plated steel construction provides a durable, corrosion-resistant mounting surface suited to the damp environments typically found around filtration installations.
  • Hardware Included: The bracket comes complete with the mounting hardware needed for installation, eliminating the need to source separate screws or fasteners on the job.
  • Complete Filter Kit Compatibility: Designed to work as part of a full point-of-use filter kit that includes a white polypropylene bowl, black polypropylene filter head with pressure relief button, two 1/2" MPT x 3/8" compression adapter fittings, a full circle filter wrench, and an AS568-237 NBR O-ring with a spare.
  • No-Lead Standard: Manufactured to a No Lead / Lead Free standard, supporting use in potable water point-of-use systems.
  • Secure Filter Support: Provides the structural anchor point that keeps the filter head and bowl properly seated on the 3/8" compression connections during service and cartridge changes.

Boshart 14A-MBS-03 – Frequently Asked Questions

1) What comes with the Boshart 14A-MBS-03 filter kit besides the mounting bracket?
The 14A-MBS-03 ships as a complete point-of-use filtration kit: the L-style zinc-plated bracket with its mounting hardware, a white polypropylene filter bowl, a black polypropylene filter head with pressure-relief button, two 1/2 inch MPT x 3/8 inch compression adapter fittings, a full circle filter wrench, and an AS568-237 NBR O-ring plus one spare. You do not need to source separate screws or fasteners for the bracket.
2) What size supply lines does the Boshart 14A-MBS-03 filter kit connect to?
The kit's two adapter fittings are 1/2 inch MPT on the filter head side and 3/8 inch compression on the tubing side, so it ties into 3/8 inch supply lines, the common under-sink size. Inlet and outlet both use the same 3/8 inch compression connection, and the bracket is what keeps the head aligned to those lines so the compression joints aren't strained.
3) Can the Boshart 14A-MBS-03 bracket be used for drinking water?
Yes. The 14A-MBS-03 is built to a No-Lead / lead-free standard and is intended for potable point-of-use water applications, including under-sink taste and odour systems and residential filtration rough-in.
4) Will the L-style bracket mount inside a sink cabinet or does it need a wall?
Either works. The L-shaped profile lets the filter housing sit flush against a wall, a cabinet panel, or the side of an under-sink cavity, so it suits tight point-of-use installs where the assembly has to stay out of the way. Mounting hardware is supplied with the bracket.
5) Do I need a special wrench to change the filter cartridge on this Boshart kit?
No separate purchase is needed. A full circle filter wrench is included with the 14A-MBS-03 kit, and the filter head has a pressure-relief button so you can bleed pressure before unthreading the bowl. A spare AS568-237 NBR O-ring is also supplied for the bowl seal.
6) Is a zinc-plated steel bracket going to rust under a sink?
The 14A-MBS-03 bracket is zinc-plated steel, which gives a corrosion-resistant surface suited to the damp conditions around a filter housing. It is the structural anchor for the head and bowl, so the plating matters when cartridges are changed and water gets on the bracket.
7) Can the Boshart 14A-MBS-03 filter kit be used in an RV water system?
Yes. Recreational vehicle water systems are one of the listed applications for the 14A-MBS-03, along with under-sink taste and odour filtration and residential rough-in. The bracket holds the housing fixed, which matters in a vehicle where an unsupported filter bowl would work the compression joints loose.
8) What is the exact part number to order the Boshart L-style filter mounting bracket kit?
Order Boshart 14A-MBS-03. That is the single model for the L-style zinc-plated mounting bracket supplied with hardware as part of the point-of-use filter kit.
