Boshart C075NL No-Lead Bronze Barb Insert Coupling for Poly Pipe
The Boshart C075NL is a no-lead bronze insert coupling built for joining poly pipe runs in rough-in water service applications. This barb-style coupling is part of Boshart's bronze insert fitting line, engineered with a smooth sweep channel geometry that minimizes friction loss and maximizes flow rate and pumping efficiency through the fitting body. It is available in 3/4" and 1" sizes to match common poly pipe rough-in requirements, and it is designed specifically for use with poly pipe — not hose. Each unit is supplied in a package quantity of 10 each, making it a practical stocking item for contractors and distributors handling rough-in plumbing supply.
Key Features
- Available Sizes: Offered in 3/4" and 1" barb sizes to cover the most common poly pipe rough-in and service line diameters.
- Barb Insert Connection: Dual barbed ends are sized for insertion into poly pipe, allowing a secure clamp-and-crimp style connection typical of poly pipe rough-in work.
- Durable Bronze Construction: Cast bronze body resists corrosion in below-grade and wet rough-in environments, standing up to long-term burial and water exposure better than plastic alternatives.
- No-Lead Compliant: Manufactured to no-lead specification, making this coupling suitable for potable water rough-in installations where lead-free fittings are required.
- Smooth Sweep Channel Design: The internal flow path is engineered to minimize friction loss, ensuring the highest possible flow rates and pumping efficiency compared to standard insert fitting geometries.
- Poly Pipe Specific: Designed exclusively for poly pipe systems — this fitting is not intended for use with hose applications.
- Contractor Pack Quantity: Supplied 10 each per package, suited to bulk rough-in plumbing stock and job-site inventory needs.

Why Boshart?
Boshart's bronze insert fittings are built with a smooth sweep channel design specifically to reduce friction loss and deliver dependable flow performance across the 3/4" and 1" poly pipe rough-in sizes offered in this coupling family. The no-lead bronze construction gives plumbers and contractors a corrosion-resistant, code-conscious option for connecting poly pipe runs behind the wall or underground, backed by a manufacturer known for purpose-built rough-in plumbing hardware. Stocking both available sizes in the 10-each contractor pack helps distributors and installers keep rough-in jobs moving without waiting on special orders.

Boshart C-075NL – Frequently Asked Questions
1) Can I use the Boshart C075NL barb coupling on garden hose or is it poly pipe only?
Poly pipe only. The C075NL barb insert coupling is built for poly pipe systems and is not intended for hose applications, so the barb profile is sized for insert fit into poly tubing rather than a hose ID. For hose work you need a hose-thread or hose-mender fitting instead.
2) Is this bronze coupling okay for potable water lines?
Yes. The C075NL is manufactured to no-lead specification, which is what potable water rough-in requires for a metallic fitting. Note it does carry a Prop 65 warning for lead, which is a California disclosure requirement and separate from the no-lead construction spec.
3) Do I need clamps with the Boshart barb insert coupling or are they included?
Clamps are not included. A barb insert coupling is secured by sliding the poly pipe over each barbed end and tightening a clamp over the pipe at each connection, so you will need two clamps per coupling, sized to the pipe OD. The package ships 10 couplings, which means 20 clamps for a full pack.
4) What sizes does the Boshart no-lead bronze insert coupling come in?
Two sizes: 3/4 inch (MPN C-075NL) and 1 inch (MPN C-100NL). Both are dual-barb couplings for joining two lengths of poly pipe of the same nominal size. There is no reducing version, so a 3/4 to 1 inch transition needs a reducing coupling instead.
5) Will bronze insert fittings hold up buried underground better than plastic ones?
That is the reason to spend on them. The cast bronze body resists corrosion in below-grade and wet rough-in conditions and stands up to long-term burial and water exposure better than plastic insert fittings, which is why bronze gets specified on underground water service and well lines rather than nylon or poly inserts.
6) Can I use this coupling to repair a split in an existing poly water line?
Yes, that is one of its intended uses. Cut out the damaged section, insert the barbed ends into each cut pipe end, and clamp. It is listed for poly pipe coupling repairs and extensions as well as new-construction rough-in, underground water service, and well and irrigation runs.
7) Is the Boshart C075NL sold individually or only by the box?
It is supplied 10 each per package, one size per pack, which suits distributors and contractors stocking rough-in inventory rather than someone needing a single fitting.
8) Does the insert fitting restrict flow on a well or irrigation line?
Less than a standard insert fitting. Boshart's bronze inserts use a smooth sweep channel through the body to cut friction loss, which matters on pump-fed well and irrigation runs where every fitting eats head. It is still an insert fitting with a reduced ID compared to the pipe, so count it in your total friction loss.
