Spears 474-E Series PVC Bulkhead Tank Adapter
The Spears 474-E Series is a workhorse PVC bulkhead adapter prized for its balance of chemical resistance, low cost, and broad availability — making it a top choice for general-purpose bulkhead hose barb applications. Compared with polypropylene or nylon options on this list it is typically the most economical and easiest to solvent-weld into standard plumbing systems, though it trades off some high-temperature performance versus CPVC and some impact strength versus nylon designs.
Rugged PVC — tank's pal
Easy slip-install — ninja-fast

Banjo TF100 Polypropylene Bulkhead Tank Fitting
Banjo's TF100 polypropylene bulkhead fitting is chosen for aggressive chemical environments and lighter-weight installations because polypropylene offers excellent resistance to a wide range of acids and alkalis while staying economical. Against the Spears PVC it often provides superior chemical compatibility, and versus the CPVC Hayward it is more chemical-tolerant though lower in maximum continuous temperature; compared with nylon it generally costs less while sacrificing some mechanical toughness.
Polypropylene toughness — farm-ready
Low-profile barb — less bulk

Review Summary
"Buyers like the TF100's chemical-resistant polypropylene body and straightforward installation for sprayers and tanks, though some report minor seepage if washers or tightening are not done correctly."
Corrosion-proof — hates rust
Polypropylene body resists a wide range of agricultural and industrial chemicals.

Hayward BFA1020CES CPVC Bulkhead Fitting
The Hayward BFA1020CES uses CPVC to deliver higher temperature and chlorinated-water compatibility, which makes it a market-leading choice for pool, spa, and hot-water bulkhead hose barb needs where thermal performance and chlorine resistance matter. It commands a premium over PVC and polypropylene parts but provides technical advantages for hot or chlorinated systems that the Spears, Banjo and nylon fittings do not reliably offer.
CPVC corrosion-proof — pool pal
Smooth flow interior — swim-ready

Review Summary
"Owners report solid CPVC durability and good pool-grade finish with long service life, but several say it is pricier than generic options and requires proper torque to avoid leaks."
Tool-tight seal — leak-shy
CPVC construction tolerates higher temperatures and pool/chemical environments.

Green Leaf BHN100P Nylon Bulkhead Hose Fitting
The Green Leaf BHN100P is a nylon bulkhead hose fitting engineered for mechanical durability, offering greater impact and abrasion resistance that suits rugged or moving installations. It stands out from the list by prioritizing strength and dimensional stability over the lower cost of PVC and polypropylene, and while it typically resists wear better than those materials it can be more sensitive to certain solvents and elevated temperatures than CPVC.
Nylon strength — greenhouse buddy
UV-stable design — sunproof
