KobraJet 4000 PSI Pressure Washer Hose — Stainless Steel Fittings + Inline Swivel | 50', 75', 100'

MTM KobraJet Hose - Built the Right Way by a USER!

Most pressure washer hoses are an afterthought — stiff, prone to kinking, fitted with cheap brass hardware that corrodes and leaks. Treated as a secondary necessity to the pump, when it's one of the greatest compliments you can add to your setup. This KobraJet was engineered for professional detailers and serious enthusiasts who can't afford downtime.

Rated to 4,000 PSI. Single-wire reinforced construction stays pliable in all conditions — no memory, no frustrating loops, no fighting the hose while you work.

What Sets THIS Hose Apart?

All-Stainless Steel Fittings — Standard Across Every Build Unlike competitors who reserve stainless hardware for premium tiers, every KobraJet ships with stainless steel fittings on both ends. No corroded brass. No seized connections. No mystery metal.

Built-In Stainless Steel Inline Swivel — Included on Every Hose Every KobraJet hose includes a stainless steel inline swivel fitting that allows the hose to rotate freely as you move. This single feature eliminates the most common frustrations with pressure washer hoses: the hose laying flat when it wants to loop up, twisting underfoot, and coiling back on itself mid-job. Your hose follows you — not the other way around.

Hand-Assembled In-House Each hose is custom-built by hand. The machine-side features a 3/8" stainless steel plug; the spray end ships with a live stainless steel swivel coupler (3/8"). Every fitting connection is sealed with Loxeal 83-54 Engineering Adhesive (Italy), then torqued and torque-marked — so if a fitting ever backs off, you'll see it immediately. No guessing. No mystery leaks.

Non-Marking Sheath Available in Grey (textured outer jacket) or Blue (smooth non-marking jacket with printed protectors). Neither will leave scuffs or marks on driveways, garage floors, or paint-corrected surfaces.

Temperature Rated Handles spike temps to 310°F and continuous use at 275°F — compatible with hot water pressure washers.
