All components that are used in the production of Jarp cylinders and swivels are high quality, close tolerance, reliable parts that stand up to Jarp's high standard for product durability and performance. Most of the internal cylinder components and swivel stems are made of high-strength ductile iron to withstand higher loads.
Oniy the highest quality seals are used in Jarp cylinders and swivels to prevent leaks at higher pressures. High quality wear bearings eliminate metal-to-metal contact to protect the cylinder from scoring.

The quality of Jarp cylinders and swivels doesn't stop with the components. Each cylinder tube is skived or honed after fabrication to ensure a precision fit for internal components. This costs a little more than prehoned tube, but the improved performance and reliability is well worth the cost. Jarp's in-house capability ensures a precise fit and a 16 RMS finish for reliable performance. Each and every cylinder is fully pressure tested on Jarp's custom designed test stand prior to shipment. Jarp test stands are monitored and maintained to the highest ISO cleanliness standards. This assures the customer that they are getting an excellent product with the highest reliability.
